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.
Ford Super Duty (1999-2016) :: F250 5.4L - Engine Idle Rough - Missing / Shaking When Giving Slight Acceleration
I have a 1999 F250 Super Duty 5.4L, 118,000miles...engine seems to idle somewhat rough but tach doesn't seem to move off 1000rpm & when giving slight acceleration seems to act like its missing, shaking . But under acceleration moderate or high purrs like a kitten! Always starts good , few cranks. Any hints on the what issue might be?

I have a 95 Impreza with the 1.8 motor, this thing is hesitating when you give it too much gas at once. I got the car this way so I don't know when it started. I put in new plugs, the wires tested ok, and the ignition coil tested ok too. The only code the engine was throwing was 21 the coolant temp sensor and that has been replaced. I also put in new o2 sensor, maf sensor has been cleaned. Checked for vacuum leaks and there are no leaks, also did a compression test and got 180 on all 4. Where to look next, I don't want to just replace sensors without knowing what is wrong. The car did run better with the tps sensor unplugged but still running very bad.

I am trying to track down a problem for a friend with a 2001 Passat, 1.8L. The car has 150k and had a timing belt about 50k ago. About 3 weeks ago, it started misfiring badly on idle. In gear driving around, it purrs like a kitten. I scanned for codes and got:
Address 01: Engine
Controller: 4B0 906 018 CL
Component: 1.8L R4/5VT G 0001
Coding: 16551
9 Faults Found:
[Code] ....
At first I thought it might be a vacuum leak, but it looks like when he took it in 2 weeks ago they replaced all the vacuum hoses. It is unclear when he last had sparks and coils. I understand the likely culprits are:
sparks
coils
ICM
I am hesitant to blame sparks/coils if he is getting misfires on all 4 cyl. It seems like they might have screwed up the timing belt install given the camshaft sensor error, but he's been running for 50k miles since the change, and this idle issue just appeared recently.
Golf IV / Jetta IV :: 2005 GTI 1.8t - Rough Idle And Misfires
2005 gti 1.8t having really rough idle and misfires at idle fine while driving pulling codes:

P0302
P0304
Unplugged MAF and didn't make a difference...
Golf IV / Jetta IV :: Rough Start And Idle But No Misfires
I have an 03 vr6. I'm getting codes p0300, 0303, and 0304. I changed the plugs and the coils and still has changed nothing. In the morning when I first go to start the car it has a rough start and idles rough. But after letting it warm up it is fine. It drives perfectly fine, no misfires. None of this started happening until the car ran hot a few weeks ago. Did a compression test and everything came up fine. So would could my issue be? I'm at a loss here. I was thinking fuel issue but if it was a fuel issue, wouldn't it run rough all the time?

I have 11 tiguan 2.0T. When I start it up is runs rough below 1200 rpm. The check engine light starts flashing. The codes are all 4 cylinders for random cylinder misfire. When I go drive it around the roughness calms down but doesn't go away and the idle will start jumping up and down. It goes to 1500 back to 800. Then 1700 back to 800. It had even hit 2400 once. I have changed the pcv about 2 months ago. I checked it and it looks fine. One place said maf. I cleaned it and no change. Running out of options.

I have a 04 FX4 scab with a 5.4L and am having issues with it idling rough, and low power and stumbling upon acceleration and cruising speed. I did a scan and the codes show lean run condition, misfire on cyl 4, etc. I changed injector and coil on #4 and it seems worse. Scared to change the plugs, until I can leave the truck down a day or two in the event that I break one or more.

After a long trip from Houston to Dallas, my vehicle started to ride rough and eventually die on idle. It seems to idle fine, but then die after the first minute. I am getting code P306 and others all dealing with random misfires and misfires on ALL cylinders. The troubleshooting steps I have taken so far to no avail are:
(1) Replaced spark plugs with pre-gapped iridium
(2) Checked ignition coils
(2) Checked all vacuum hoses and air intake leaks
(3) Changed air filter(not a big deal)
(4) Removed and cleaned the throttle body with carb cleaner thoroughly
(5) Checked the intake manifold for leaks and did not find any.
(6) Computer PCM checked for updates and issues at dealer
The dealer said it needed new fuel injectors, which seemed kind of fishy due to the following symptom:
The car runs GREAT at highway speeds, but it is unable to maintain an idle for an extended period of time and dies due to misfires. I hear a chugging in the engine sometimes.
Due to these symptoms, I self diagnosed this as a fuel regulator?
Ford F-150 (2009-2014) :: Random Misfires On Cylinder 1 / 3 And 4 - Rough Idle
Ok so I have the 2009 f150 4.6l 2wd. Have random misfire codes. Horrid idle. I replaced all of the spark plugs, coil packs, and even the injectors on 1/3/4. Still codes nothing is better. I'm thinking maybe an intake manifold leak,? I see no real signs but I do hear that little pop pop pop. Now I have a gasket kit for it but I see you can order complete manifold kits with thermostat and gaskets on amazon for like 60 bucks more. The issue is I see none that fit my truck. Is it the same as the mustang? Hate to blow more cash as its adding up.

2005 Ford F150 lariat 5.4
I had a misfire under a bit of a load (acceleration) and up hills. I changed spark plus with OEM Motor craft ones, truck ran super nice for a couple week.
Had the engine light flash, slow down and the RPM go up a tiny bit then back down and the light goes off
Now I'm back to miss fire different location, and a rough idle. I've swapped coil packs around and the miss fire stayed on cylinder 4.
Spark plug screwed or injector or ?????
Touareg :: 2004 V6 Engine Hesitating And Not Reacting
Exhaust signal on MFI ... Yesterday in the morning this sign came few times blinking and then became solid. I felt like the engine was "hesitating" and not reacting. Later on the day it disappeared.
This morning came again. When I check the manual at section 3.1 page 39, it says something about "not enough oxygen..." Its been cold here in Charlotte NC, around 28F overnight and I am leaving the car on the driveway since we moved to a new home. Should I rush to the dealer?

View 8 RepliesPrius (2004-09) :: 2006 128K - Error P0A08 / Throttle Has Been Hesitating On Acceleration
I got the Check Engine/VSC/Triangle of Death errors yesterday. Autozone reports it is P0A80 (replace Hybrid battery) though no additional details reported.
I'm the original owner, and after some reading suspect it could be something else because:
1. In 8 years, the starter battery has never been replaced.
2. For about two months, the throttle has been hesitating when first accelerating (within first five minutes of turning it on). Yes, it is the hot summer months (though mild compared to previous summers). And the hesitation occurs even in the morning before things really heat up. This is definitely even worse after the error lights came on.
I've seen recommendations to replace the starter battery first. And other recommendations for "throttle body cleaning." I'm not a mechanic, but obviously would hate to have the hybrid pack replaced if it is something else.

Touareg :: 2004 V6 138K Miles - Rough Idle In Neutral And In Drive When Stopped
Recently noticed the idle seems rough in Neutral and in Drive when stopped. When the roughness is subtle, that RPM gauge doesn't move and at other times with more pronounced surges the RPM gauge bounces around. Not sure if it is related but we just got back from a couples days in Tahoe. Tried reconnecting the gas cap with no change.

I'm new to diesels. I just bought a 2004 F250 with the 6.0 V8. I have the high and low circuit, contribution codes on cylinders 4 and 8. I've only had the truck for a few days but I've been reading a ton. The symptoms are hard start, rough idle/shaking, no power when cold. When it heats up and I'm over 2000 RPM it seems to be just fine. Even when hot and below 2000 RPM it does ok. I've check the FICM. It reads 48V with key on and 48V running. My plan is to do the following:
Change the Fuel Filters
Change the oil filter
Change Air Filter
Change oil with 5-W30 synth and I have both Hot Shot/Rev-X
If that doesn't work, I'll replace the two injectors. How does that sound.
