Sonata NF (2006-10) :: Rough Idle / Lack Of Power Under 2000 RPMs
I have a 06 sonata 3.3L v6. I have been having misfire problems and lack of power under 2000 rpms and at idle when I am either a stop or just warming the car. What is happening I feel it shake and feel the misfire but after it gets up after 2000 rpm at highway speeds its completely fine. It struggles getting up to speed if i press on the accelerator. I have changed the spark plugs and all the ignition coils maybe about 2 months ago, I have also have changed the camshaft position sensor for the rear bank. I believe that it could be the crankshaft position sensor but I want to make sure....

I have a 2002 F350 4wd with the 7.3. I was driving the truck and all of a sudden it was running like crap. the engine light was on. after a minute or so the engine light goes off and the truck is running fine. then again starts running like crap. I am close to the house so I limp it home. runs like crap.... will barley climb small hills. engine light is on. get home turn it off... next day... starts up and runs great for 10 - 15 min. engine light comes back on... runs like crap.... my neighbor says "It's the crank position sensor" I replace it.... runs great for a month.... now it's doing the same thing......
View 9 RepliesAccent RB (2012+) :: Rough Idle / Stall At Stops And Tough Time Accelerating
Noticed this to be a problem with our older 2011 Accent, now with the 2012 Accent.
The car has a rough idle usually in mornings, it seems like it is going to stall at stops, it also has a tough time accelerating.
The computer scan does not show there is anything wrong until the problem becomes worse.
This is what I have discovered through the 2011 Accent. Car will stall at stops. Very inconvenient in rush hour traffic. Until they replace the Crankshaft Point Censor, the problem would not go away.
I would insist on looking at this rather than replacing sparkplugs or having any other service performed if one is experiencing these same symptoms. The good thing is it is under warranty.
Nissan - Sentra :: 2005 - Won't Start Easily - Rough Idle On Start Up?
I have a 2005 Nissan Sentra with 74,000 miles on it, and it has had trouble starting for 2 or 3 years. When it started, I would turn the key and the car would almost, but not quite, start, and simply turning it off and trying again would work immediately. I had the battery replaced and the spark plugs at ~50,000 miles to no avail. About a month ago, I started my car and it had a really rough idle for about 15 - 30 seconds and the check engine light came on (registered an emission issue), but it ran fine. I had to get a routine oil change and emissions test anyway and they checked the spark plugs as a first measure. They all had some wear, but one was almost worn down to nothing, which the mechanic said was a result of the spark plugs (autolites?) so they replaced them with the Nissan recommended NGK kind. The next day my car didn't start the first immediately, but on second try worked. A week later I noticed my car sometimes rumbling on idle right after start again, so they replaced the fuel filter and the fuel pump. Didn't work, I still have a rumble about 30% of the time when I start, and just two days ago the check engine light came back on (I haven't had time to get it diagnosed yet). Without knowing much about cars, it feels like the engine isn't getting enough fuel or something. Could it be dirty/clogged fuel injectors? Should I be worried that my spark plugs were worn down after just 25,000 miles?

We have a 1995 Nissan Pathfinder (automatic) that is having trouble starting. We can't find a pattern to when it starts and when it doesn't start so we can't diagnose the problem. When it doesn't start, here's what happens: turning the key, you can hear one soft click. Then nothing. After several or many turns of the key (and the same single click), it finally "catches" and starts. Two weeks ago, the car would not start at all. Even the following day, it wouldn't start. The lights and radio did work. We tried a jump-start and it surprisingly started right up. We immediately replaced the battery, but the problems resumed. The following have been replaced since the problems began: starter, ignition switch, battery, transmission, and the horn for the alarm has been bypassed. Note: with the old battery back in, it does work.
View 5 RepliesNissan - Juke :: Comparing 2002 Pathfinder With 2006
I have a 2002 Nissan Pathfinder and I love it. I bought it in 2006 and it has 156,000 miles on it. I am ready for something and here are the options. Buy another 2002 with low mileage for all the reasons you all know about that year and the 2003.Just great years. I have found a couple with mileage around 75,000 for around 8,500. My daughter wants my car and I am going to have a tune up done on it for her. Nothing wrong with it at all, Or get for me a 2011 Juke. I don't know why but I love that car. Been told I won't get much better gas mileage unless it stays in the eco mode. I can pay cash for the Pathfinder. Will have to finance the Juke. Makes me nervous that it's sort of new but I have heard from those who know that it's a good car.
View 14 RepliesNissan - Pathfinder :: 1994 - Intermittent Inability To Start
My 1994 Nissan Pathfinder will intermittently not start. When I get in the car and turn the ignition, the dash board lights will light up as usual, I can hear the starter solenoid click, but then nothing will happen. The power windows, stereo, headlights and air-conditioning will all work but the motor will not even churn. All I hear is the click. If I get a jump the car will start right up.
This has been going on for over a year. At first it would only happen every few months and I thought that by just disconnecting the positive from the battery and putting it back then it would start. It appeared to be doing so. When it started happening more frequently, I took it my mechanic and each time he would fuss with some wires charge me 20 bucks or not charge me at all and I would be on my way. It would be good for a week or so then once again not starting for me.
After the three times of my regular mechanic not fixing the problem and saying it was fixed I took it to a different mechanic. This man said it was my starter even though it will start with a breeze if you jump it. I went ahead and had him replace it. My car started a few more times but the next day the problem was back. After having gone to two mechanics and them misdiagnosing and me paying for service I didn't need, I borrowed a volt meter and the battery test at 11.5 volts. Some buddies said, that perhaps my battery being 14 years old was putting out enough power to power the cars electronics but not enough to turn the starter over. So I bought a brand new battery. I got four starts off of it before I experienced the problem again.
Another friend thought it might be the alternator not fully charging the battery. I believe we tested it at 12 volts but he said it should be more. Anyway, he and I pulled the alternator took it to be tested and it's fine. While we were removing it though we discovered the belt on the alternator was a little loose so maybe it wasn't charging fully. Anyway, we put it all back together and the car started five or six times, while my more knowledgeable buddy was with me. The next day of course, no start.
I probably did a bunch of stuff I didn't have to do in trying to diagnose this problem but at least I learned a lot more about my car. Anyway, ye wise car sages, What do you think is wrong with my old car, which for the most part has treated me well for all these years? Ignition? a short somewhere? If it's the ignition perhaps you can explain to me why the vehicle will start with a jump.
Nissan - Pathfinder :: 2006 - Heater Malfunction - Won't Blows Hot Air When It Is Stationary?
This one has me stumped, and I can't find a rational explanation on the net but it appears to be a known problem. I have a friend with an '06 Nissan Pathfinder that has climate control with dual zones (front and rear) that fails to blow hot (in front) when the vehicle is stationary and the rear heater is on. I used to wrench for a living so I've eliminated the obvious. The front blows hot air when the vehicle is in motion and also when stationary and the rear climate controls are off. So clearly it would seem to me that the issue probably lies in the switching of ventilation ducts from hot to cold. I'm not familiar enough with the system to proffer a solution though. The way I see it it's probably a sensor at best, an issue with the climate control unit itself at worst, or some sort of bizarre mechanical malfunction involving the vents closing when they should be passing air from across the heater core to the entire interior.
I haven't spent much time diagnosing the issue mainly because I don't do it for a living anymore. Hot air comes out of the front when the car is warm, stationary, and the rear blower motor is off. My friend who isn't very technical and speaks English as a second language tells me that when the rear heat is on it blows cold in the front while the vehicle is stationary (in Park or perhaps just when stopped for an extended period i.e. at a traffic light).
Nissan - Pathfinder :: 2002 - Slowly Crank And Eventually Start
Will try to sum it up: Most of the time, the thing starts like a charm, first try. Every now and then, though, I'll turn the key and either a) nothing will happen or b) it will slowly crank and eventually start. If nothing happens, I have always been able to try again seconds later and everything works OK. Have been through several batteries. Current battery checks out OK, as does starter and alternator.
A short circuit, perhaps? If so, how would I check it out? Problem with taking it to a mechanic is, most of the time all is OK. No pattern as to when the trouble will occur (has yet to happen with vehicle in the shop, of course).
Nissan - Pathfinder :: Won't Start - Battery / Alternator / Starter Fine?
I have a a 2003 or 2004 Nissan Pathfinder (can't remember which at the moment). For the past few months, it's been having the same problem. One morning, I'll go out to start the car and the radio will have stopped working, but everything else is fine. A few days later, however, the car won't start in the morning. I'll jump it off, and the car and radio will be fine again for a few weeks. This doesn't last for long though.
Eventually, the radio will go out, and a few days later the car won't start again. I took it to my local mechanic and they tested the alternator/battery/ starter and said they were all fine, and that the battery cables just needed to be cleaned. After the cleanup, the car and radio worked fine for a few weeks...but sure enough, a few days ago, the radio went out. This morning I had to jump my car off again. What the real problem is? I'm taking it to the shop again today, but what else it could be...
Ford 6.0L Power Stroke Diesel :: 2006 F250 - Rough Start And Idle When Engine Cold
Truck has been doing this and now getting worse. 06 f250 6.0 147,000 miles. Runs like crap when you first start and truck has trouble shifting when I first take off in the mornings until it warms up then it idles fine and runs like a champ no problem shifting. Not in a cold climate 40F at the least. Not trying to take it to the dealer and get raped. Been doing research some people say get the inductive heat flash, some say needs new injectors, some say could have a bad gasket on the injector idk. I'm trying trying to get it resolved....
View 4 RepliesNissan - Pathfinder :: 1999 - Won't Start Smoothly - Engine Fired Very Little And Then Knocked Off
When cold engine starts on the first attemp 80% of the time, when warm its about 60-70%. Sometimes it take 2-3 attemps to start. But on the second to last attemp the engine will fire very little and then knock off.
So far I replaced the distributor, spark plugs and wires, boost sensor?, fuel pressure regulator, and checked the injector ohms and fuel pressure at the engine with the old pump. After replacing the fuel filter it started fine for a few days, after replacing the fuel pump it started fine for a week. Thus making me believe it's a fuel issue. So I added check valves to the fuel line at the engine, both the supply and return lines. And still few days later it's back.
Nissan - Pathfinder :: 1998 - Replaced Plugs While Diagnosing Misfire Now Start But Won't Run
1989 Nissan pathfinder. 6cylinder - VG30i - Manual trans
Engine was misfiring (running okay but putt, putt, putting) so I pulled be plugs to check for signs. Other than wear and wide gap the plugs looked okay, but I installed new plugs as they're cheap and I was already pulling them. I replaced them one at a time so didn't mix up the wiring. I went to restart the engine and now it turns over and starts but then immediately dies. If I really slam on the pedal I can get it to rev up a couple times, but it really wants to completely die right away. It'll start but won't run
- I took the battery lead (neg) off for a few days - maybe that reset something?
- I had a very empty gas tank - so low that I thought it might be out of fuel. I put two gallons in just to make sure. Because I can slam on the gas and get it to revving I'm not sure being out of gas is the issue.
- I removed the distributor cap to check for wear but reinstalled (picture attached).
- I sprayed some Mass airflow sensor cleaner into the throttle body to clean up, the throttle body valve blade was pretty clean.
- I'm doing this test without the air filter in. The old one was so dirty I removed it and didn't bother putting it back on. Going to buy a new one today.
- It cannot pass smog due to this misfire (obviously not detonating fuel so it's polluting)
- The engine was start up readily before I started tinkering. It would seem strange that adding new plugs
- I didn't gap the plugs.
Next steps :
- Look for any wires knocked loose or hoses disconnected.
- Pull the error codes (check engine light is on cuz, it's not running)
- Check Vacuum and diagram and hoses.
- Check ignition system wires.
- Check fuel pressure.
- Check Cylinder Compression.
Ultimately I'm trying to tune it up (and fix misfire) anyway, not just change the plugs, so doing more diagnosis is okay. It's also not my primary car. I haven't worked on cars in a while so I'm a little rusty and also needing to get necessary tools to complete the tasks. But it's fun I hope I can get this car running well again soon.
Nissan - Pathfinder :: 2002 - Take Long Time To Start - Fuel System?
My wife's Pathfinder (a 2002) has developed a problem with slow starting. The car cranks well (even at -20F, so it's not a weak battery) but takes a long time to start. It might crank for 5 seconds before sputtering to life. After being driven and shut off, most of the time, it will start up instantly again, just like it used to before the problem started. The problem is intermittent in that it sometimes starts pretty quickly in the morning, although it's not the instant start that it used to be, it might only crank for 1 second or less. I know that sounds like a normal time for a car to crank before starting, but the Pathfinder used to start, almost literally, instantly after the key was turned. So, even 1 second is an uncharacteristically long time.
What I've done:
-- Replaced spark plugs
-- Swapped the starter relays with identical relays under hood
-- Replaced fuel filter
What I haven't done:
--Replaced fuel pump
--Replaced fuel pressure regulator
Both of these are somewhat big jobs (I think I can handle both of them) and more expensive than what I've already done, so I'd like to get some input on where the fault could lie before picking one. Or, am I completely off base thinking it's fuel system?
Nissan - Pathfinder :: 2005 Won't Start / Ignition Related Fuses Are Fine

View 13 RepliesNissan - Pathfinder :: 2005 Losing Power While Driving
My 2005 Nissan Pathfinder with approximately 150,000 miles has been losing power while driving. It's pretty scary. The problem first manifested one week ago when it stalled at a stoplight. It restarted after a few panicky moments of frantic key turning. My husband and his identical twin brother took a look under the hood when I got home and discovered the terminal on the battery was loose and had a screw in it to maintain a closer fit. They remedied that by replacing the screw with aluminum foil. Four days later, I'm driving away from a large big-box store, and it loses power again. I got it restarted and drove around back of the store to the tire center. They tested the battery, and declared it "bad".
The battery and the terminals were replaced. Hooray! I was safe. Or so I thought. The very next day, I drove out to the middle of nowhere to go fishing, and it lost power three times. I was an hour away from home and there was no cell phone service. I left the lake before dark and lost power once more on the way home. To recap, the first time it lost power I was stopped at a light, the second time (at the store) I was at a stop sign, the third, fourth, and fifth times I was driving but slowing down for cars in front of me and had to pull over to restart it, and the last time I was driving down hill and the power came back on before the bottom of the hill. A lot of lights come on in the dashboard when it loses power.
Regal :: Buick 1995 Shuddering / Rough Idle And Lack Of Response When Accelerate
I have a 95 Buick Regal, V6 3.8 Liter. The symptoms are the following: stuttering idle. And lack of response at times when I try to accelerate. Like sometimes I'll be driving on the highway, and having no problems. Then I'll be going up a hill at around 55 mph, and then the car will shudder as I try to maintain a speed of 55 mph. So I have to ease off the accelerator and slow down. At first I thought this was a transmission problem, but I am guessing it's the same problem that causes my choppy idle.
So I had this acceleration problem on the highway when I was going up a hill. And a weak idle. These problems have been going on for several months now. They were annoying, but didn't seem that serious. Then all of a sudden, on a rainy day, the car was really responding poorly to acceleration at all speeds. I was able to drive around, but I couldn't count on the car responding right away when I hit the gas pedal. And the car would shudder at times. Then, I didn't drive the car for a few days, and then it was dry, no rain, and the car ran better. So I am thinking humidity makes the problem worse.
I have also noticed over the past few months, that the car runs best when I start it up after a few days of not running it. Then if I drive the car a few miles and let it sit for about 2 hours or so, it would idle weakly when I would start it up again. The car's been doing that for several months now, but it wasn't really affecting the drivability or the response of the car when I hit the gas pedal.
Now it's gotten much worse. So, I've already replaced the following items myself to no avail: mass air flow sensor, oxygen sensor, and egr valve. I am guessing the next thing to fix is the pcv valve. But I also think it might be the fuel pump. My first guess though is the pcv valve. What else could it be? And is there any easy way to test to see if the fuel pump is going bad? Or should I just take out the pcv valve and see if it looks bad?
Nissan - Pathfinder :: Power Steering Pump Is Intermittently Engaging / Disengaging
I have an '05 Pathfinder w/ 93k miles. Recently noticed a uneven feel in the power steering, most noticeable at slower (less than 30mph) speeds. Feels like the power steering pump is intermittently engaging/disengaging. As I turn the steering wheel I feel random "tight" or "hard" spots in the steering. Similar to what you would feel if the wheel was against a curb and you were trying to turn into it. Doesn't make any appreciable noise, but can just feel it in the steering wheel.Checked power steering fluid, no issue. Replaced power steering pump, had no effect. Power-flushed the power steering system, had no effect.Oh - and my wife says she hasn't hit any large rocks, logs, or potholes recently!
