Passat (B5) :: 2003 VW GLS 1.8T - Rough Start / Idling And Misfiring On One Of Cylinder?
I haven't started my passat for the winter and I finally did today. It was ruff start/idling and I pretty sure it was misfiring on one of the cylinders. I turned off the car and start it again...same thing, ruff idling like 3 cylinders were running. I waited five 5 mins and started it again, then it was a normal start on all cylinders. But the engine light came on, even though it started properly. I know I have to clear the code to get rid of the engine light. But I want to avoid any future misfiring. So I'm thinking new spark plug/coil overs.

I have a 2003 passat 1.8 and I just started having a misfiring problem. I googled it and ran across a 2003 press release that VW had recalled them. I am going to call tomorrow, but I did a little testing myself. Probably not the best thing to do, but this is what I did. I had my wife start the car and I pulled off the coils until I hit the one that didn't make the car shake any more than it already was. It is the second one from the front. I pulled the spark plug out. It is the original, but didn't look too bad.
My question is: How do you test the ignition coil to see if it is faulty or if it could be the distributor? The coil that attaches to the plug looks a little burnt around the rim where it connects to the plug. Its not an expensive part, but I don't want to go buying another one just to find out it is the main distributor or something else...
Ford Ranger / B-Series :: 2003 - Misfiring On Start Up - Got Codes P0316 And P0304?
My 2003 ford ranger 3.0 v6 is having a misfire on start up and it is located in the forth cylinder. Where to start to get rid of this problem. i have already changed all my plugs wires and even the coil pack cleaned out the maf and looked for possible leaks. the car shakes really bad at lights and the check engine light starts to flash. Need diagram of where all the cylinder numbers are at and maybe the firing order?

03 6.0 with 90k miles. New heads, all orings , stand pipes, injectors , glow plugs, egr delete , oil cooler and studs . Has sct livewire. Just took the truck to the shop for a hard start issue and misfiring at around 30% throttle driving. It would fire up great in the mornings with some white/blue smoke till warm. But after it was warmed up you shut it off it would fire right back up but very slow to reach proper idle.
But if it set for about an hour it would crank great start but same lazy idle up but now it wouldn't get over 300 rpm before it would die. And do this for 5 or so more times before finally idling up. Then runs pretty good other than the misfire. So he said it's either the hpop ipr or icp. I had him replace all 3 with motorcraft parts. Still the same issue ! Return the truck to stock tune and it doesn't have any power . My pockets are only so deep...
Passat (B6) :: 2006 2.0T - CEL On And Cylinder 3 Misfiring
My dad has 2006 passat 2.0T. In December 2010 he went overseas. During his absence the car was parked in garage and not in use.
So one day I decided to start the car and as soon as I turned it on the car made this noise and check engine light came on. Took the car to a private repair shop and found out the cylinder #3 was misfiring. The tune up for this car was due so I had all four spark plugs changed and the car ran fine for few days. Then couple of days later it started making the same sound and this time around the coil for cylinder #3 was replaced.
A few days after that check engine light came back and this time it was blinking and the engine was struggling to run, took it again to the workshop yesterday and this time another coil not sure which cylinder was replaced. (all this is done at a private workshop). I have a hunch that the car is going to run fine for a day or so and the problem is going to come back
I never had any major issues with it up until now. Bought this car new in 2006 from dealer. I am afraid that this might be a start of a downhill roll from here on I will drive the car tomorrow and see how it reacts.

I've been out of town a bunch and my car has been sitting out at the airport. I picked it up last friday, drove it home. Today on my way to work the car started jerking - like the engine was trying to rev slightly. When I put it in park, and listened, the engine was jerking or misfiring maybe. The exhaust was a bit louder than normal as well and i could hear the stress in it. I also smelt a strange burning smell. I've called and had roadside assistance pick it up and take it to the dealer.

I have been working on a 2001 VW Passat 2.8 for a while now. I replaced the engine for a customer. Now its misfiring bad.
I did a compression check, everything there is good
Leak down test - everything good
Replaced plugs
Replaced coil pack with known good one
Replaced spark plug wires with good ones
Its missing on 1, 5, 6, some times 4, sometimes 3
I have check all my vacuum lines, no leaks. Sprayed throttle body cleaner every place I can think of, and no change in idle.
I did replace the timing belt, but that is all good. Start's right up. Just shakes bad.
I did check for spark at the plug wires and its getting really good spark.
Passat (B6) :: Hesitation And Misfiring Only During Heavy Load
I have a 2008 Passat Komfort Wagon with the 2.0T. At 40,000 miles, yes it only has 40,000 miles, the thing started hesitating and misfiring on me only during heavy load. I ran the codes and it said #4 cylinder misfire. The check engine light was only on during the time it was misfiring and hesitating. Took it to the VW dealer to have them run it again and get guidance and they verified the #4. When I picked up the car the CEL was illuminated. They said it does it when it misfires. I explained that it was not on when I dropped it off and they basically said tough cookies. So I replaced the #4 coil pack and all 4 plugs. CEL light still on, but wasn't misfiring. Next day it began misfiring again under heavy load. Took to Autozone to run the codes and now says misfiring on all cylinders.
View 6 RepliesPassat (B5) :: Idle Very Rough / Misfiring - ECM Dying
B5 passat. Recently she took her car to the shop bc her cel was on. turned out her turbo was blown so she got it replaced with a brand new one along with the oil pump. about 3 days later the check engine light comes back on..idle is very rough and it feels like its misfiring.
First thing i did was check the coilpacks bc it was why my audi would always misfire but it didn't work. So she took it back to the shop and they said that her ecm is dying. Ive never heard of that happening.
The codes that came up from the CEL the second time were p0171, p0172, p0173, p0303
Golf IV / Jetta IV :: Won't Start - Misfiring - CEL Came On?
So leading up to today ive had some bucking under load which felt like misfiring to me. I borrowed my friends VCDS cable, checked MAF, checked o2 sensors, checked cat. They are all good. This problem is constant but i did get a misfire code once (random, cyl 1, 2, and 3). I cleared the code and they never came back.
Today as im driving home from work, the bucking problem was much worse. Then the CEL came on. I just checked the code, and it was system too lean. I cleared the code and now the car will not start. It cranks, shows rpm on VCDS and sputters but doesnt even come close to starting.
Touareg :: Misfiring While Accelerating From A Cold Start
For the past few weeks, my Treg has been misfiring while accelerating from a cold start. It only does it when the engine is first started and only the first time you accelerate. Also blows blue smoke out the tailpipes while this is happening. Car is at the dealership right now with a tech and Service Manager scratching their heads. I already did a search for my problem, nothing matched it.
View 9 RepliesPassat (B5) :: 1999 1.8t Misfiring At Idle And Battery Light Flashing
I got a 99 1.8t. Here's the deal, misfiring at idle, flashes battery light. alt and battery was checked and there great. it has a maf code, so I unplug the maf and still get the same misfiring. maf was fine be4 i tried cleaning it, now it throws the code. it had misfiring be4 i clean it also. next problem is it stutters and misses if i go wot in 4 or 5 gear and the batt light flashes it doesn't throw a misfire code. Also if I am idling and i floor it, it stutters and misses at lower rpm rage and then is fine at higher rpm range. i replaced plugs and gapped em right, i did a power balance test and the coils all are firing so is the injectors. I don't got vag but i do got a good obd2 scanner i was looking at the data wen car was off and i seen that if i floor it the tps only reads 77.7% . Also my timing says its 12 degrees and idle fuel pressure is fine i checked with a gauge. Pretty much misfiring with no codes thrown and flashing battery light.
View 17 RepliesToyota - Corolla :: 1996 - Misfiring After Hard Start
About a month ago I went to get into my car and it would not start. It tried to but after testing things with my neighbor there didn't seem to be consistent spark. So I bought a new distributor. Got it installed and the car worked great. Then after about a week we had a heavy rain while I was driving. The car shut off and wouldn't start. After the rain was over for about an hour I went to look over the car and it started. I thought with the heavy rain something got wet. Then things really went down hill. A day or so later when I went to start the car it didn't want to start and when it did it would misfire. Later that day the car started fine but would only run right if the engine was warmed up.
I tried covering the car completely with a tarp, no change. My cousin who is a skilled mechanic said he was pretty sure that the issue was the new distributor. So I got a used one, not wanting to pay another large amount again. Put that in the car and no change. So I pulled the plugs on the car. Plugs 1 and 4 had a heavy carbon build up on the tips with pitting in the carbon. I had had them replaced, with the wires back in October. So I replaced the plugs and coated the wires in liquid electrical tape. Car started fine like it does in the afternoons. Nest day it was raining and I went to see what the car would do. It started! I drove it that day with no issue at all. The next day I went to start the car thinking my issues where over. The issue has returned. I changed out the plugs with new ones that night. Car started fine that night. Next day the car is still not wanting to start and misfires when it does. It has been damp but covering it doesn't change anything.
Dodge - Durango :: 2001 - Won't Start / Misfiring Periodically
I have a 2001 Dodge Durango with the 4.7 liter V8. I recently changed the spark plugs and it ran for a few days misfiring periodically. Then overnight after a good day of running it would not start. The engine will rotate but not fire. I changed the individual coils but only to get the same result. I think that I may have the wrong spark plugs but where to go next.

I just bought a 2000 ford explorer which didn't start... I put a new fuel filter, spark plugs and air filter in it...still not starting ...gonna do a a compression test tomm. and see if it the timing chains or tensioners... Sounds like its misfiring actually, it doesn't start with starting fluid sprayed in it....where is the ignition pickup located on these things? I still need to put a new ignition coil and wires on it. plugs were in horrendous shape and i thought that was the problem.
View 13 RepliesPassat - Volkswagen :: Misfiring On Cylinder 3 - Carbon Build Up On Intake Manifold
I recently took my 2007 VW Passat 2.0T in b/c the check engine light was on. They initially replaced a leaking valve and a bad ignition coil, but the car was still misfiring on cylinder 3. They took off the intake manifold and found that there was significant carbon build up. The service writer said it was from "low-quality" gas. The car requires 91 octane. I've used 93 octane since 2007 but started using 89 octane around 6 months ago when the gas prices spiked again. Could 6 months of 89 octane cause significant carbon build up to the point it would trip the check engine light? Or could something else have caused it that I need to watch out for?
View 4 RepliesPassat (B5) :: 2001 - Misfiring - Got Codes P0300 / P0301 / P0302 / P0303?
i have a 01 passat with a v6 in it on 4 motion and im having an issue with soem mis-firing
i pulled the codes. P0300 P0301 P0302 and P0303 which are all saying that there are missfires in cylander 1,2 and 3 and random miss fires.
im also getting a P0340 which is cam sensor A or the right hand bank. problem is i just replaced the cam sensor and when the motor got warm, the code came back. I was told by the previous owner that the car needed a Coolant Temp Sensor....can this be the cause of my mis-fire issue? hear me out.... it only happens when the car is warm so im thinking that the car is warm but the ecu thinks its cold cause its not getting a good signal from the CTS. thus its either advancing the timing as if the motor is cold and cuasing a miss fire or something along those lines. any thoughts?
