Dodge - Ram :: 2005 - Hesitating Under Acceleration At Lower RPMs / Shaking Feeling In Steering Wheel
About 2 weeks ago, my 2005 Dodge Ram 1500 4x4 4.7L, was running fine. The very next morning, it's 4.7l engine has a very obvious misfire situation where it's hesitating badly, especially under acceleration at lower rpms, with the shaking feeling in the steering wheel etc etc. I have Advanced Auto parts and 2 separate auto shops plug in their little boxes to find the problem codes. The check engine light came on and stayed on as soon as this issue began. The codes they got were consistent from place to place: 1. Misfire on cylinders 4 & 6, and 2. Random multiple misfire.
So I go and buy 2 brand new coils for cylinder 4 and 6, and 8 new champion plugs. I was in Florida for a week, so the truck was NOT driven at all after the day this problem began. So I replace all 8 plugs and install the 2 new coils, but it makes NO DIFFERENCE. It's still hesitating just like before. Today I take it to Goodyear to have them do an allegedly thorough evaluation. They use their little code box and they get the same codes as mentioned above about random multiple misfire and misfire on cup 4 and 6.
Then the mechanic takes the truck for a ride and experiences the same hesitation and shaking under acceleration. So he replaces both of the new coils I had installed with their coils and replaced the 2 new plugs, just to make sure there was no issue with these new parts. He takes it out and apparently plugs in a different computer that monitors all engine functions, including air/fuel mixture, spark etc. According to that computer, the truck is running properly(according to them), and he checks compression and says it's good. So what's wrong, and he said that my car's computer was reset so the check engine is no longer on(I am not clear the how's and whys of that part). But the important thing is that it's still running badly and they can't tell me why it's running badly!
The mechanic said maybe a lifter collapsed or there is sludge that's causing an issue, but no solid explanation. Supposedly the 4.7L Dodge engine has a sludge issue experienced by some owners, and the mechanic recommended replacing the oil every 1500 miles instead of 3000. By the way, I asked how much it would cost for Goodyear to check the lifters and check under the valve cover, but he said they don't do that.
Celica :: 1987 GT Won't Idle At Lower RPMs
I have a 1987 Convertible Celica GT, with Manual Transmission. The car will not idle at lower RPM. I had someone look at it, and they have it where it will idle at 2000 RPM, but anything lower than that, and the engine will die when not giving it gas.
The engine accelerates great and runs great at any speed, but if you push in the clutch without giving it gas, it will die, unless the idle speed is cranked up like it is now. What this might be?
Ford - Escape :: 2001 - Low Power / Missing And Shaking When Going Up An Incline
2001 Ford Escape or later and having problems with missing, low power and shaking when going up an incline. I have had problems with my escape for the last two years missing and missing and more missing. Have replaced Coil packs and spark plugs several of them. Well back in June I let the Mechanic have it for almost 3 months. All 6 coil packs were changed, spark plugs included, all vacuum hoses, belts, water pump, front CAT already had new radiator replaced last year. Had two broken wires leading from the PCM to the fuel injectors 1 and 5, he re did the wiring harness there and checked the fuel injectors.
After all done that could be done, I took my car back and it was purring like a kitten, on a flat surface that is............after driving it for several days, headed to another city and had several small inclines to go up, not bad ones, and between 45 and 50 mph, my escape started to shake, miss, and make noise, not a loud noise, but enough to get my attention, and the check engine light started going on and off. Today I took it back to my mechanic, he went on a test drive with me, (me driving) and it duplicated the problem. Went back to his shop, put the code machine on it, and no codes, I asked him if he had serviced my transmission like I asked, and he checked with his other mechanics and they said no, that the transmission fluid seemed okay, figured it didn't need it. Well guess what it did. So if ya'll are till having problems after you have replaced the coil packs, check for electrical issue around fuel injectors, and your front CAT, mine was full of fuel, then make sure you service the transmission, and you'll have the best little ride ever!!!
Camry :: Battery Light Came On While Driving - Rough Idle / RPMs Lower Than Usual
Yesterday my mom used my car and the battery light came on while driving, but she didn't really care about it and was driving the whole time on the battery. When she came back home the car was barely even alive I couldn't even start it. I replaced the alternator (duralast from auto zone) and the serpentine belt, but now I have a very rough idle and the rpm's are lower than usual. They are 1500 instead of 1750. Is this normal and eventually it'll go away or did I mess something up?

View 2 RepliesStalling - Ford - Focus :: Rough Idle / Shaking When Gets Under 1000 RPMs
I have a 2008 Ford Focus - 4 Door Sedan SE 60300 miles.
I've gone to 3 mechanics now and no one can seem to figure out whats wrong with my car. Here's whats happening:
About 1 1/2 years ago I took my car to get an oil change at Jiffy Lube (Yeah never again). When I left, my car was idling funny... Silly me didn't take it right back and have them tell me what was wrong.. so I let it go, well about a month later it started idling even weirder. Basically it feels like my car is shaking when it gets under 1000 RPM and I notice my RPM dial start falling and bouncing back, acting like its going to stall, but never does. I notice a loss of power when this is happening (on speed up and just accelerating in general). All of this is random, I can't seem to put a pattern to it as to when it happens. One day I'll start it up and everything is perfect... Then I'll shut it off and restart it later, and it starts vibrating and puttering again... No signals as to if its hot/cold or wet/dry, no environmental variables seem to cause it to happen anymore than others. And there is no check engine light on, everything "looks" normal.
What I've had done to it so far is:
Air filter changed / reseated
3 oil changes (keep getting told it will work)
Throttle cleaned
Computer reset for idle sensor data rebuilding
Now I'm told that I need new engine mounts, and that could be the reason for the vibration. I'm thinking that the vibration caused the mounts to wear out, more so than the mounts being the cause. Mainly because I don't see how bad mounts could cause loss in power/bad idling.
What could be wrong?!? Really bugging me and don't want to keep throwing money at it for phantom solutions. Seems like mechanics I go to can't figure it out unless there is a check engine light on with some diagnosis code to tell them exactly whats wrong.
Ford F-150 (2009-2014) :: 2011 - Hesitation From Idle - Missing Or Running Lean / Rich During Spin Up Of RPMs
I have recently purchased a 2011 F150 Ext cab with 3.5L ecoboost with 69k miles. I have no experience with these engines prior to now. I've always wanted a full size truck and after driving my 98 S10 for 17 years, I decided it was time for a new truck. I hope I made the right choice in going for the 3.5 instead of 5.0.
On to my question. I've noticed that the truck hesitates from a dead stop or anytime the RPM's are under 1k. It feels like its missing or running lean/rich during the spin up of RPM's. When I drive it hard, it does seem to subside for a little, and I've heard people say that they run better when run hard. I can attest to that, but is this hesitation normal for an almost 70k mile engine? I am getting 15ish MPG on almost all city driving since I have bought it, but I do expect that to change (job hunting and current commute is less than 2 miles each way).
The only time I get to open it up is when I go run errands out of the immediate local area or visiting friends and family. On one of those trips, before I noticed the hesitation, I attempted to accelerate from 60 to pass on the expressway and it bucked and resisted like a horse. It finally took off up to 80 and completed that journey with no issue but the check engine light came on for a bit. The check engine light went off when I shut it down and hasn't come back on since.
New ride: 2011 3.5L Ecoboost....
Ford Ranger / B-Series :: 2001 B3000 V6 Missing In 2 - 3k RPMs And Jerks?
2001 M B3000 v6 my sons truck w 122k. He is overseas and I took it to deliver a CB750 bike to my brother in law... 4oo miles away from my place.
In the middle of nowhere TX it developed a bad miss or knock, almost a shudder in the 2 to 3 k rpm range. Idles ok just below 1k runs fine at 70 mph as long as the rpm is near or over 3k.
Not sure I want to turn around and drive back the 400 with it running like crap. I will take it to Autozone and pull codes tomorrow a.m. but what should I expect?
Civic - Honda :: 2001 - Belt Squeal In Lower Gears / RPMs
I've got a 2001 Honda Civic, automatic, that has a nice (what I think) belt squeal going. It seems to happen when it's wet/cold, in the lower gears/RPMs, when the defroster and/or rear defroster are on. SOMETIMES it will stop when I turn off the defrosters. If it persists I can make it stop by quickly putting it in park (at a light or stop sign) and right back into D or if moving gunning it for a few seconds. Occasionally I do get a hot rubber smell (like a burning vacuum belt) coming through as I accelerate. So as someone with no real car knowledge, does this sound like a belt issue that I can take care or myself (i.e. belt tensioner and a gauge) or should I just leave it to the pros?

I have a 2004 SD with 5.4 that is running pretty rough both at idle and driving. Truck shakes a lot at lower rpms. I have a scan tool and had a misfire on cylinder 4 so I replaced the coil and the plug. Also replaced the idle air control valve. Plan on replacing O2 B1 S2. (One of my codes) even after replacing the coil and plug I'm still getting misfire detected from cylinder 4??? Other codes I had were misfire detected on he first 1000 revolutions. That hasn't come back though.
View 2 RepliesFord 7.3L Power Stroke (1999-2003) :: 2001 F350 - Missing And Shimmy - RPMs Will Drop A Little
I ran out and test drove a new to me 2001 F350 7.3L tonight. Everything seemed good, until I got back from the test drive. I pulled in and was sitting there with it idling. It seemed to idle fine, then a very small miss and very small shimmy then idle fine again; then another small miss and another shimmy. It continued like clockwork. Every time it seemed to miss and shimmy, the RPM would drop just a little, but not much. Does an ICP sensor sound like the problem, or maybe something more serious? 2001 F350 7.3L with 235,733 miles new trans, turbo replaced at 150,000 something miles. No blow by. Idled fine before driving, also drove fine. It doesn't seem to surge when idling, just kind stalls and shimmys for a split second then idles fine for a few seconds.
View 1 RepliesElantra XD (2001-06) :: Intermittent Missing At Idle
I have a 2003 Elantra GLS that has two issues that may be related. The first one the engine will shut off for no apparent reason. Doesn't matter how fast, or if the a/c is on or not. I used to be able to start it right up after I pulled over, now I have to wait about 15 seconds. Starts up fine and runs like nothing happened. There is no particular time frame when it will shut down. Maybe once a month, then happen twice in a week.
Second issue is when I have to stop at a red light and have the a/c on, it seems to have an intermittent miss, meaning after it does miss it idles fine for a while and then misses again. It seems like a miss to me, feels like the car almost shuts down but catches itself and will idle fine until next miss. If I turn off the a/c I do not feel it miss. If I have the a/c on and put it into neutral, it does not appear to miss near as much.
The check engine light has come on twice for a day or so and then goes out. Car runs fine when it does. Below is what I have done since I purchased the car used at 104,000 miles. current mileage - 117,000
* changed timing belt, transmission fluid, brake fluid, changed oil at 104,000 miles when bought.
* installed new radiator recently
* installed crankshaft sensor (due to error code when checked)
Other than that, car runs great, accelerates good, idles good
Santa FE SM (2001-06) :: Power Loss - Vibration / Missing When Idle
My father owns a 2003 Santa Fe GLS with the 2WD 2.7L V6 engine.
Recently it has been having lots of power loss issues. It vibrates/misses when idling, if you put your foot down on the gas pedal, whether under load or not, it sometimes stalls or just sits there. We took it to Hyundai, and they had no error codes. They charged us $150 to tell us nothing is wrong with it, when clearly something is. The car has become downright dangerous to drive because it cannot make it up hills without stalling/losing power.
The most recent thing we had done to it was the wires/spark plugs changed, which I think was at 65k on the odometer?
Santa FE SM (2001-06) :: 2004 - Slight Missing At Idle That Occurs All The Time
I will occasionally get a misfire after a rain storm, lasts about ten minutes then goes away. there is also a slight miss (no CEL) at idle, that occurs all the time. I'm thinking spark plug wires.... the plugs were done last year, but nothing else. to my knowledge the wires and coil packs are all original. i'm at about 114K on a 2004 santa fe 3.5l.
Also, does the computer store misfire codes? I know I got them in the past and i checked it at the time, but didn't write down what cylinder it was. think it'll still be in memory?
Think it's ok to change just the wires and not the coil packs? kind of on a budget...
Santa FE SM (2001-06) :: Cylinder 3 And 6 Misfire / Shaking When Idle
I just felt that my 2005 Santa fe shakes when idle in front of a traffic light today, later on the check engine light illuminated. Drove to a Monro shop right way and diagnosis using their professional OBD reader, it turns out that the Cylinder 3 and Cylinder 6 are misfiring according to the OBD scan result.

Recently with the rain and snow my truck has started missing but only around 2,000 rpm in lower gears. its a 1996 chevy k1500, it has new plug wires spark plugs and new distributor cap and rotor. When its dry outside it runs fine and everything is tight so I'm thinking it has to be the tower or coil.
View 1 RepliesElantra XD (2001-06) :: Low Idle / Power Stutters At Mid RPMs Upon Acceleration
So my 2001 Hyundai Elantra GLS with 80,000 miles, I bought it with 70,000 off of Craigslist to use as a daily driver while i rebuild my honda s2000. Anyways the trouble I am having is that on a cold start the engine idle is almost normal like it should be but the engine just runs really rough and shakes. I do not have a misfire. However the current check engine light was an evap light in which i just removed the charcoal box completely from the system and closed off the vacuum lines. I then unhooked the battery and of course the light went off. I drove it down the road and ir still has the power loss but the cel did not come back. So cel fixed and i hoped the idle would improve but it hasn't. I do not know what to do next...I have read in other threads to check the intake gasket and i will i was just wondering, what this problem could be and how to fix it. As for emissions i don't really care. I have a buddy that will pass the inspection.
View 2 RepliesHonda - Cr-v :: 2001 Stalls Almost When In Gear Or Even When RPMs Fall To Idle
Have a 2001 CRV that is running really bad. It almost stalls when I put it in gear or even when the RPM's fall to idle. It is now throwing a p0172 code. I have a simple scan tool and verified the MAP reading and primary O2 voltages as suggested by the manual, both appeared to be normal. It seems all the symptoms point to valve clearance, however the valve were adjusted not 2000 miles ago by the dealer during the 150K service, and this issue has existed before and after that adjustment. I also cleaned the IAC screen with no changes.
