LS / MKZ :: 2000 LS 3.9 V8 - Started Idling Rough / Code P0171
I have a 2000 Ls 3.9 V8 125,000 miles that started idling rough.I checked for codes and got p0171 (bank 1 lean), p0175 (bank 2 rich) and p0307(cylinder 7 misfire). I swapped cop and sparkplug from cylinder 7 to cylinder 5 and erased the codes.I ran the engine for a while and rechecked the codes to see if the misfire followed the cop and plug. They did not. I still get p0171,p0175 and p0307 (cylinder 7 misfire).

Our Accent has just about 86k on it now, back in November it suddenly started running real jerky/rough, misfiring kinda thing. So I was able to drive it to my local repair shop and they found a bad coil pack on #3, so they replaced that and put in new plugs while they were doing it.
Just Saturday we were shopping about 20 miles from home and cranked it up to go home and started doing it again, pretty much identical symptoms, runs out normal at certain RPMs so I knew it was probably same thing...I was able to get it home and then took it in this morning and sure enough now #1 is shot. So they are replacing that. They want about 30$ more per coil then I can order them for myself online so I didn't want to scarf up the money for the other 2 that are still original.
Rough - Mazda - 626 :: 1999 - Rough Idling But Runs Fine At Higher RPM
This problem has been getting worse over the last 2 years. When the car starts it idles fine at about 1000 RPM. As soon as it warms up, it starts to idle rough, between 500 and 750 RPM. It almost quits running. As soon as you give the car some gas it runs just fine. About 3 weeks ago I got a "Engine Lean" check engine light error. I reset the system and have not gotten the error again. Since then I have: changed the MAF cleaned the EGR (made sure it closes completely and ohm out the coils in the actuator) changed the O2 meter on the exhaust manifold cleaned out the throttle body Ohmed out the air idle controller. What I should check next. I was planning to check the fuel pressure in case it is a fuel system problem. It is a 1999 ....

My daughter returned from college with her 2000 f150 4.2 idling and running rough on acceleration. It is throwing a P0171 code only. I replaced the isolator bolts/plenum gaskets four years ago because of a P0171 & P0174 codes.
So far I have replaced the MAF, new PCV valve and elbow, checked all obvious lines for vacuum leaks (though I suspect a leak somewhere still). Also, a quick check of the plugs show some lean color/deposits on the drivers side only. Any thoughts or troubleshooting I should try next?
Accent LC (2000-05) :: Slight Stutter / Hiccup When Idling And Transmission Slipping At 2k RPM
2000 Hyundai Accent GS, 1.5l, 4cyl SOHC...
I have a slight issue. A few weeks ago, I put some "STP" style fuel injector cleaner into my gas tank. Either A) It cleaned everything really well and clogged my injectors, or it turned into gunk and possibly clogged something else up.
Ever since that day, my issue is that the car "stutters" very slightly. When idling, it'll "hiccup." When I'm doing normal driving, 55-60mph at 2k RPM, It'll almost feel like a transmission slip.
I've went and replaced my Fuel pump, filter, and now I've done half a can of seafoam through the brake line power booster (vaccuum) straight into the engine, and the other half into my oil for further cleaning. I also applied Seafoam Deep Creep into my throttle body, just for further maintenance.
Ever since then, everything has been running noticeably better, and I've had a huge increase in gas mileage, but there's still a slight hiccup that occurs during idle and driving.
I change the oil /filter, plugs, wires, air filter on a regular basis.
I also had to change the MAF at one point in time, as it died and the car wouldn't start at all.
Next thing I'm thinking about doing is changing the plugs / wires one more time (it's been about 5 months since my last change) just to see if I bought a faulty plug.
The car was put on a computer and the only error code that came up was one about my check engine light being out.
Prius C :: HV Battery Fan Running Higher Than Normal On Freeway
Recently installed a curt trailer light. I modified the V plug in harness to work with the C.
I noticed the fan was running louder then usual. I took the right rear panel off were the HV exhaust vent it and there is no ducting from the factory.
The battery duct just goes to the back of the seat and vents out in that right corner right behind the 12V.
It makes its way up and over the right rear tire tub then what ever comes out of the rear exhaust, just vents out with momentum from down below. No duct guiding it from what I can see?
I went back and zip tied a wire that was in the path to sides were other factory wiring runs.
This seemed to fix the issue after making everything neat?
Not sure what caused it but it seems to be from wiring that was in the way? When I run the HV fan with my SG and remove the shock tower assess cover on the passenger side. I can feel hot air coming out. This might be an easy way to get more exhaust venting for anyone that wishes to do that.
Accent LC (2000-05) :: Started Kind Of Rough Then Knocking / Tapping
I own a 2001 Accent 1.6, auto. 150,000 well-taken-care-of miles. New plugs/wires/timing belt/coolant flush 10,000 miles ago. Most recent oil change was with Shell Rotella T5 (I believe 10w-30 blend) and Purolator PureOne filter, 4-5,000 miles ago. It does not burn any oil, and runs very well. It has never been low on oil, revved high, or abused in the 10,000 miles I've owned it (except an ebrake u-turn on a dirt road to scare the wife )
The engine has always had a mild tick when cold, that goes away within about 30 seconds. Normal, from what I could tell. Also, it has always had a tick from roughly 1500-idle when releasing the gas, in neutral. Again, seems fairly normal for a little engine, I figured just some valve noise.
This morning I started the car (sat overnight) and it idled a bit rough for about 20 seconds, and I noticed that the ticking from before was now closer to a knocking/tapping, nowhere NEAR the horribleness of a spun rod on my WRX . But it was still a bit alarming. It never really quieted down, but as I rev, the sound goes away completely above 2k, and the flutter when I release the throttle is louder than before.
Accent LC (2000-05) :: 2001 - Running Rough After Filling Up
A few weeks ago my car was running perfectly fine, i filled it up with fuel and then it started running a bit rough. Would drive ok but could feel it surging and if i backed off on the accelerator it would try stall.Also the fumes in the car were a lot stronger than usual. Got home and it stalled, started it up and was idling rough and blowing black smoke :/ no engine light has come on though. I did the typical thing and googled possibilities, the mojority said that it was the purge control valve so i replaced that with a new elantra one (part numbers were the same) and its still running rough We are now thinking it could be the oxygen sensor? Have checked vacuum lines and stuff for air leaks and cant find any. Unplugged the oxygen sensor while car was running and it made no difference at all.. If the oxygen sensor was working properly it would of affected how the car was running, right?
View 1 RepliesAccent LC (2000-05) :: Running Rough When Cold But Only When Accelerating
My 2000 Accent 1.3 has developed a problem recently: starts fine and revs freely and smoothly when parked. When I pull away it will get very rough like it's firing on only 2 cylinders or so, at certain points during the rev range rather than continuously. Very juddery.
After a minute or so, before the engine temp is even up to normal operating temp (according to the dial) it runs perfectly. When I start it up later the same day it's fine. It only happens the first time in a day that I use it. The more days I go without driving it the worse it is.
In the last couple of years I've changed spark plugs (always in good condition when I replace them), HT leads, coil pack, a lamda sensor (the first after the exhaust downpipe) and a fuel pump and filter.
Accent LC (2000-05) :: Intermittent Misfire / Running Rough
I have a 2000 LC that has a few symptoms - intermittent misfire/running rough at these times it has:
dark smoke
uses 3 times the fuel
loss of power (to normal)
will pick up revs slow without running rough and runs normal at high revs.
dies misses and then picks up revs slowly when accelerator is pushed fast to the floor from idle.
Hyundai mechanics checked computer and it coded change spark plug leads this did not fix the problem, and have no idea.
About 6 months ago the car was doing the intermittent thing when it died and liquid was heard splashing on the ground. I found the main petrol line connecting to the pump had come completely off. After replacing all problems ceased and the car ran perfect with full power etc.
I've checked the fuel lines none appear to be leaking etc.
Ford A/C :: Temp Gauge Running Higher / Showing Above Normal Temps
My temp gauge (which very seldom deviated form its position) is showing above normal temps. Yeah its over 90 here but this is unusual for my car to run hotter. I put in a new thermostat about 3 years ago. I've also been adding water/anti-freeze because there was a small leak (that I finally found in the hose) that I corrected. Could it be that my mixture isn't a 50/50 mix or is it my thermostat again? They say they don't last long anymore???
View 1 RepliesAccent LC (2000-05) :: 2004 - Automatic Transmission All Of A Sudden Started Slipping While Driving
My 2004 Accent transmission with 145k miles all of a sudden started slipping while driving. It would be fine until i needed to slow down and then step on the gas again. It wouldn't catch right and it would slip. At first the pull of the slip was very slight and at times now it is very rough. My check engine light does not turn on when it slips slightly, but only when it has a really rough slip will it turn on. I had it checked at the local advance auto parts and i was told it has a 4th gear ratio that is off. The only thing that confuses me is that when i turn the car off and on it resets and works fine, that is until it slips again. If i drive carefully it usually wont slip. Could it be an electrical problem?? I changed my speed sensor when my car had about 132k miles because it went out, i replaced my ignition coils, new spark plugs/wires, tranny oil change, and filter change.

I have a 2001 Accent GL 1.6L Automatic.
Yesterday it started acting up on the freeway. I was driving about 50 during traffic hour when it started revving. I got off the freeway and moved to 35mph on surface streets, the revving continued at lower speeds but much worse (4-5k rpms going 10-15mpg). Doesn't seem to do it in idle or park. If i shut the car off it'll drive fine for a while then start acting up but when I was driving, after awhile, it did return to normal.
What could cause the problem? TPS? Transmission? Sensor of some sort?
Ford - Explorer :: 2004 - Transmission Hesitate For A Long Time Between 2 - 3 Gear And RPM Went Higher Than Normal
04' Ford Explorer - 4.6l Automatic 4x4 - 138,000 miles... While driving today my transmission hesitated a long time between 2-3 gear and RPM went higher than normal. After coming to a stop a taking off again, long hesitation, slams into 3rd gear, check transmission warning came on and OD light on dash was blinking. I drive it home and pull the code: P0745. I drop the pan and find a piece of metal 1/4 wide x 1/2 long. Does this mean a complete trans rebuild?

View 16 RepliesPassat (B6) :: Higher Pitch Of Faster Turning Engine / Car Idling At Higher RPM At Stop
Sometimes I will stop at a light and my idling rpm will go from 600 (usual rate she idles at) to about 950. While this may seem inconsequential in the grand scheme of things, it's noticeable enough that it seems like the car wants to go. It'll lead me to depress the brake more. You can also hear the higher pitch of the faster turning engine (it is a 50% increase in speed). This will happen at random times so I have not been able to pinpoint if it is caused by a particular driving style. ECM for this?
View 7 RepliesSubaru - Forester :: 2000 Started Shaking At Higher Speeds
My 2000 Forester recently started shaking while driving at highway speeds or while under engine load (hills, accelerating, etc). My first thought was that it was a problem with the alignment so I took it to my local tire shop. The car has 164K on it and has been without a Subaru specific mechanic since my last guy got fired a year ago, though I am trying to get an appointment with the only other Subaru mechanic in the area, outside of the dealership.
The tire shop found an issue with cupped tires (naturally they'd want to sell me tires) and told me that my passenger side rear CV joint was bad and they'd have to replace the axle. Since this sounded credible for the symptoms it was showing and they found me an axle, I told them to go ahead and replace it.
When I got it back the first time, I didn't see any great improvement in the shaking. I also noticed that they'd forgotten to put the bolt back into the bottom of my shock absorber. o_O When I brought it back to them, they fixed the missing bolt and agreed to keep it for a week to troubleshoot where else the shaking might be coming from. In the process, they replaced spark plugs and wires (which it probably needed anyway) and did an oil change, but the shaking is still there after all their tinkering. They suggested the problem may be in the timing and that I should have that checked out.
I don't think they're right about that. The vibration feels (to me) even more like a CV joint problem now than it did before. It shakes more violently and at slower speeds the longer it runs so by the time I get to work (40+ miles) it's almost constant. It stops shaking when you pop it into neutral and let it coast suggesting it's not timing or alignment - and making me think even more that it's something to do with the drive train.
