Golf IV R32 :: Misfires On Cylinder 5 And 6
Feb 23, 2010
How the cylinders are numbered as your facing the car from the front left to right (forgot the order) so I can replace coil packs on cyl 5&6 (238 misfires in 2min is not good).

Golf IV R32 :: Cylinder 2 Sporadically Misfires When Accelerating Up To About 60mph
My Mk4 R32 has been in the shop for a week now. My number 2 cylinder began sporadically misfiring on the highway and then once I turned the engine off and then back on it would run fine until I got back on the highway and began to accelerate up to about 60.
Took it in and the mechanics couldn't replicate the code. Got a vacuum tube replaced and and it ran fine until I got to the highway. Same issue.
At this point the fuel injector has been replaced and its still throwing the code.
Golf/GTI VI :: 2010 - Code Read P0303 Misfires Cylinder 3 Detected
I recently bought my 2010 gti used with 62k miles on it about 3weeks ago. The car had an carbonio intake stage 1 and a stage 1 tune from Apr when I had bought it. On the test drive and for the first two weeks I had it I did not have any problems. A few days ago on a cold start my car threw an MIL and it was flashing. When I got to school I plugged it into the obd2 scanner. Code read P0303: misfire cylinder 3 detected.
My teacher and I went over possibilities of the misfire. Coil pack, plugs , injector, valve float( even tho this should not occur at 1300rpm cold start) we also thought that maybe because the car is direct injection the valve was not closing all the way due to carbon build up on the top of my valves which in this case I'm glad I don't have an interference head. I moved around the coil packs. What is the cause of this? I'm only misfiring at start and when the engine isn't warms up to operating temp.
Prius (2004-09) :: Misfires On Cylinder 1 And 3, Now 2 And 4
2005 Prius 195k miles, oil changes every 5k +/- 500 (usually minus), new plugs at about 187k, TSBs for coolant loop done, coolant valve for ICE replaced on my dime, replaced aux battery in 2010. Transaxle fluid changed at 100k and 190k due to noise, but that is another post.
I mostly do my own work because, in general, I find dealerships to charge too much (like one hour to change the aux battery) or not competent (like changing the traction battery under warranty but leaving the seat belt behind the panel or not resetting the maintenance light during 5k Toyota covered maintenance)

I drive a 99 1.8t Passat with 90,xxx miles. Yesterday I felt the car hesitate/jerk a little when it's accelerated to 35-40 miles per hour. I've had this problem in my past and it was a cylinder misfire. I would bring it to the repair shop.
My question is: Can my car last about 1.5 weeks? My work is 20 mins away. I can definitely avoid the freeway.
Accent LC (2000-05) :: 2003 - Cylinder 2 Misfires At Startup
My accent is misfiring at startup, and randomly at stoplights. Pulling the code tells me it's the #2 cylinder. I have no trouble at highway speeds, the car really drives fine outside of stoplights and startups. The idle hovers around 900 rpm. Sometimes, once I'm on the road and driving, the CEL will go away altogether.
My main question is, is there any way to be certain that it's the 2/3 coil pack? I don't want to spend on parts that won't fix anything.

I have a 2000 lc 1.5l ... I just rebuilt the motor machine shop work and all it Will start and run for 3 seconds and then die. If I hold the gas pedal it will run but sound rough and as soon as you let go it dies I have been able to get codes multiple misfires, misfire cylinder 1, misfire cylinder 2, and misfire cylinder 4 I have put brand new plugs (copper core ngk), wires coils, crank sensor, cam sensor, iac, tps, maf and the injectors all have new orings it also has ntk o2 sensors that might have 1000 miles on them...
View 1 RepliesNissan - Altima :: 1999 - When Idling It Misfires On Cylinder 3
The car crank up normally, but when idling it misfires on #3 cylinder. When start to drive it will drive at 45 mph at full revolution but when I stop at a light the engine begins to vibrate and shakes the entire car. When moving off again, it continues to vibrate and hesitate and will not get up back in speed 25-30 mlp and now start to backfire in to the manifold. While stepping on the gas it also makes a popping sound. If I try to get the speed up any higher it will violently makes a popping sound and backfiring constantly into the manifold and struggles to go. The engine is also getting very hot although the engine gage said it normal and not overheating. If the car is sitting in a grassy area while idling it will completely burn dry the grass underneath.
View 12 RepliesBMW :: Cylinder 1 Misfires On Startup For Few Seconds Or Up To Few Minutes Under Certain Conditions
I have an intermittent start-up problem with my 2001 BMW Z-3, 3.0: cylinder 1 misfires on start-up for a few seconds or up to a few minutes under certain conditions. The misfire conditions are consistent:A)OBDII code P0313 (misfire detected with low fuel) or code PO1343 (cylinder 1 misfire with fuel cutoff). Both OBDII codes equate to BMW fault code 238.B)after winter storage it misfires on start–up for 5-10 minutes (I’ve always added a fuel stabilizer before winter storage);C)after a spike in humidity it misfires on start-up for a few seconds or up to a minute after a rain storm or;D)If I don’t run the car for a 3-5 days (always stored in a garage) it misfires for a few seconds (just long enough to turn on the “check engine” light).
Otherwise, the car runs flawlessly –plenty of power – smooth as silk - no hesitation, but with the bloody check engine light on 50% of the time.In lieu of black tape over the check engine indicator, I’ve taken the car alternately to both Minneapolis BMW dealers over the years (once if not twice a year), but the intermittent nature of the misfire and the fact that I store the car 5 months the a year has made it difficult to pin down the exact “root cause” of the problem. The dealership mechanics have swapped and/or replaced the cylinder 1 fuel injector, spark plug, cylinder coil and cable, kept it overnight and for days. The last dealership diagnosis was a defective cylinder 1 exhaust valve that could only be fixed with valve job! Yes, that’s right, pull the head and do a complete valve job - on all six cylinders. What am I missing here? What about the infamous BMW VANOS valve control system?
Ford Ranger / B-Series :: 1997 4WD - Cylinder Misfires On 4 And 6
Besides being spark plugs and wires and/or a bad coil pack, what other things could make it so i have misfires on cylinders 4 and 6? going to replace the plugs and wires later today when they get to my house but i just want to know what other things i could be so I can evaluate the potential repair cost and should the wires for cylinders 4,5, and 6 be under or over the intake manifold? I bought my truck used and they are currently under the manifold i think it would make more sense to have them over personally.
I have a 1997 Ranger 4WD with the 6 cylinder 4.0L engine. I can't remember the codes that it tripped at the moment but i think one might have been the 304 code not sure though.
I tripped the 300,304, and 306 code but don't know about any others i remembered what codes i tripped the other day when i had it scanned
Ford F-150 (2004-2008) :: Random Misfires In Almost Every Cylinder
I have an 05 Lariat with 145k miles on it. About a month ago I had a misfire code on one cylinder. Since then it's gone from once every couple of days, various cylinders. To now every day. I've had to continue driving it but the last few days it's gotten bad and I hope I didn't do any more damage(cats) but I didn't have a whole lot of choice. I've read every thread I can find and haven't found an exact match. It seems to be worse first thing in the morning, it will be down on power for a few seconds then clear up. It may not return for another 10 or 15 minutes and then cough a little and clear up.
Sometimes it will start at the beginning of a hill and not clear up until I'm back on flat, sometimes it will lose power at the top. There is zero predictability to it. I have had codes on almost every cylinder, but no single one has dominated the problem. Twice when it has been real bad I have also gotten a lean code 0174. It had new Motorcraft plugs 25000 miles ago and has run fine until recently. The ticking isn't too bad but I think I'm going to try thicker oil for the summer. It's been a while since I did the fuel filter and since it probably isn't a bad idea I'm going to do that today.
Civic - Honda :: 2002 EX Reading Misfires On 3 Cylinder And Cat Code
I have an 02 Civic EX. Engine light has been on for over a year, runs just fine. Reading misfires on 3 cyl, and cat code. I have since: changed all plugs and coils, changed both front and rear o2 sensors....switched coils around to see if code misfires changed (yes).
I see this is a common problem but no one has a solution..? I'd rather NOT change the cat converter and pay for that only to find out the light stays on. Need to smog so I can sell!
Subaru - Outback :: 2001 - Misfires On Right Side Only - Faulty Cylinder 1 / 3 And 5
I just bought a used 2001 Subaru Outback L.L.Bean, and the check-engine light is on due to misfiring in cylinders 1, 3, and 5 (right side only). I thought I was getting a pretty good deal even given the CEL risk, but the car is at the mechanic now and he is stumped and telling me I have to take it to a dealer service center.
This is a 6 cylinder with a timing chain. Plugs were replaced and computer reset and the light came right back on. There are no spark plug wires, and I read that the coil packs rarely fail. The engine runs smoothly and seems to have power, but since I just bought the car used so I'm not sure how much power is normal. It has 122k miles.
What could be causing misfires on one side of the engine only?
Passat (B5) :: 2002 - Getting Multiple CEL For Catalytic Converters And Cylinder Misfires
Getting multiple CEL's for the catalytic converters and cylinder misfires. Looking for threads that address these particular codes ie. 0431, 0421, 0300. 0303, 0306. I have a feeling that these are being caused from a vacuum leak and/or needing a reflash for the ECU.
View 3 RepliesTiguan :: Random Cylinder Misfires On All Cylinders With Rough Idle
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.
View 2 RepliesTiguan :: Running Rough During A Cold Start / Random Cylinder Misfires
I've got a 2009 Tiguan with 65k miles on it. A few weeks ago I noticed some issues with running rough during a cold start. I only noticed because the engine would vibrate considerably more than usually for the first few minutes of operation, and would idle at around 1050-1100rpm instead of the usual 750rpm. After warm up, things were fine. Suddenly the issue got bad real fast - wife was out and the MIL light came on, EPC light came on, and the car was running extremely rough. We managed to drive it home (2 miles) doing under 20 the whole time on side streets. Once I hooked it up to my OBD reader, I was seeing cylinder misfire codes on all four cylinders.. P0300, P0301..P0304, all five codes simultaneously.
Since the car was due for an oil change and hit 65k miles recently, I decided to throw new plugs in there to see if that would work. It did, at first.. A day or two it ran completely fine, no rough starts, no misfires, I thought I had solved the problem. The old plugs had some deposits on them and were original, so I thought I was in the clear. Two days later, same thing happened again.. EPC light, barely running and misfires on all four cylinders..
I read up some online and decided to order new ignition coils. Took a few days, but I got four new coils and threw them in. Again, problem solved it seemed. No more EPC light, misfire codes didn't come back and no more rough starts. I drove a good 40 miles with no problems at various speeds, but started noticing some misfires during acceleration (slightly rough acceleration, almost feels like a back and forth rocking motion, very slight). Sure enough, after a cold start I'm seeing the engine run a bit rough again with misfires. This time, only P0304 (misfire on cylinder 4) is thrown, and it only shows up as a "pending code" (engine light flashes for a few moments during start, but does not stay on).
I checked my connections, swapped the plugs and coils in what I thought were cylinders 3 and 4 (closer to the driver side), nothing. I swapped what I think are cylinder 1 and 2 (passenger side) just to be sure, but still nothing. At this point I'm pretty lost. I know enough to be dangerous with a carbureted engine, but am lacking in knowledge when it comes to a fuel injected turbo charged VW engine. It seems to be cylinder 4 misfiring consistently at this point according to the OBD reader.
Also of note.. I had some misfire problems last year, and had my intake manifold replaced as part of a recall (also had carbon deposits removed at the same time). Can a carbon build up occur this fast? Can it be the injectors?
Ford Excursion :: 2001 V10 - P0303 And P0307 Codes / Misfires On Cylinder 3 And 7
So on Christmas day I turned on my truck and all was well. I had family over and we were going up to my range to do some Christmas day target shooting. I let it warm up for about 20 minutes we then loaded up and headed out.
When I locked the hubs I soon found out my 4WD was not working? Due to the cold? It worked fine last time out and now not at all. I decided to forge ahead in 2WD, Sure enough we got stuck in deep snow. I had to gun the engine off and on to get out and as soon as I broke free (CHECK ENGINE) appeared for the first time ever. Worst Christmas ever!
The truck is running fine, full power and no irregular noise from the engine. So I ran the test and P0303, P0307 misfires on cylinder 3 and 7 appeared. This whole post is about me doing a full tune up this spring the truck is parked since Christmas and will stay parked until I do a full tune up.
New Plugs.
New Wires.
New Coils.
New oil filter and oil. Changed last year with less than 2000 miles but changing anyways.
Flush radiator and add new radiator fluid.
Clean air filter (Aftermarket, It is washable).
Is there anything I'm missing? Also, any tips on figuring out the 4WD issue?
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.
View 4 RepliesSuburban :: 1999 - While Driving After Engine Warm-up Misfires On Cylinder 2 Under Slight Load
1999 Suburban 5.7L Vortec
Symptoms: While driving after engine warm-up the engine misfires on cylinder 2 under slight load (basically whenever maintaining speed, and slight acceleration) between 1500-3000 rpm's. Backfires through exhaust when this is happening. Misfire counts on Cyl. 2 collect rapidly and only a few on Cyl. 1 but no P0301.
History: Purchased vehicle with a blown engine (intake gasket leaked coolant into engine and was hydro-locked) with the intention of using it to pull a boat or camper but never did buy either one. Replaced the engine with a new Goodwrench engine and rebuilt the tranny figuring I would drive it till the body rusted off of it. I honestly never felt that the truck ran as strong as it should have with a brand new engine but just attributed it to being as big as a cruise ship. A couple of years later started receiving multiple codes (don't remember what they were at this time) found the distributor very corroded inside due to the ear on the distributor being broken off.
Replaced the distributor, cap,rotor,plugs and wires and fixed it. About a year later, only in the summer I would start to receive the P0302 sometimes, would not happen in the winter. Did the usual plug swap, wire swap, checked spark to rule out ignition with no change. After a while the catalytic converter failed (big surprise with a missing engine) and replaced it as well as both O2 sensors on the rear bank and one on the front bank. P0302 did not change. Last year the fuel pump failed so I replaced it. This April I took the truck on a road trip to visit relatives, about 80 miles out it started backfiring through the exhaust whenever I got over 70 mph and the CEL would flash. Finished the trip babying it the whole way but now it does this all the time when warm.
Repair attempts:
* Distributor, cap, rotor, wires, plugs. (Due to distributor failure mentioned above.)
* Fuel pump and filter. (Due to pump failure mentioned above.)
* Upgraded fuel injection spider. (Because of GM bulletin regarding misfires and multiple failures found on the internet.)
* Repeated valve and fuel system cleanings. (Grasping at straws.)
* Removed rear bank cylinder head and sent to machine shop, All checked good. (After ruling out ignition and fuel figured it had to mechanical. Compression was good, cylinder leak down test was good. The problem seems to be temperature related so thought maybe the exhaust guide was mis-manufactured too tight causing it to drag when warmed up.)
* Crank sensor with a used one from a u-pull it place, I got too much money wrapped up in this. (Found a reference to this repairing a similar problem on another vehicle.)
One final note: After replacing the fuel injection spider the truck ran extremely well, this only lasted a few days and the problem came back. After replacing the crank sensor the truck again ran extremely well, but only for 1-2 days. What is the connection between the injection spider and the cranks sensor? The only other thing that I can think of that would create a misfire on one cylinder only is the PCM but that gets misdiagnosed so much that I don't want to jump to it unless all other options have been checked out.
