Passat (B6) :: Engine Running Rough And CEL On - Misfire On Cylinder 2 And 4
I'm having an issue with a 2008 Passat 2.0T. Engine ran rough one day and check engine light came on! I get the VagCom out, scan the ECU and get misfire on cylinder #2 and #4. Car has 109 000km. Plugs were never changed so I order some new OE Bosch platinum iridium plugs. Go for test drive after having change the plugs and I still get misfire on both cylinder number 2 and 4.
I know coil on plug are prone to be weak on those engines so I go ahead and order 4 new coils which are pretty low cost which is good. Once install on the car I go again on a test drive. car ran really smooth and no check engine light came on. I said fine! I fixed the problem only to discover the day after that the CEL decide to come back on I scan again and this time only get misfire on cyl #2 with fault frequency of 39.
I suspect my injector to be bad but before I decide to remove the intake manifold and spend another 2-300$ in parts. Any way to test my injector with VagCom in order to see if that really is my problem. Also heard the PCV could be a problem but i hardly doubt it would throw a fauly code on just one cylinder.
Ford Ranger / B-Series :: 2000 - Running Rough And Code For Misfire On Cylinder 3 / 2nd Coil Pack
2000 4.2....Last year I had to replace the coil pack when it started running rough and had a code for a misfire on cylinder 3. It is doing the exact same thing now, same code, same cylinder. Is there something wrong that is causing this?

I have a 2003 ranger and have had ongoing problems with misfire cylinder six and have had three different mechanics diagnose the problem as a bad ground. I have replaced all plugs, wires, coil pack, injectors and am constantly pulling the plug on cylinder six, cleaning and often replacing, I also disconnect the battery so it resets the check engine light and it runs fine for about 100 miles and starts running rough again and on goes the check engine light. I have 134000 miles and have maintained it since new.....

I have had some slight rough running with a cold engine and stumble <2000rpm. Finally it tripped a CEL which was read as a misfire code.
The mechanic swapped the coil and plug(recent) and no change. He did a compression test and air blew out the exhaust. So.......the car needs a valve job which entails motor removal and fixing the head and reinstall. He rough estimates this at $2000 and rate is $65/hr.
He mentioned looking at pistons and may be a bit more if rough.
This car well maintained (170,000 miles 2005 Legacy turbo wagon with manual)...

View 4 RepliesSonata NF (2006-10) :: Misfire On Cylinder 3 And 6 - Running Rough When Slow Down The Car
When I'm driving and get above 50-60 I will get the Check Engine Light. Check the codes It shows 6 ---300, 303, 306, 300, 303, 306. When I slow the car down it is running rough, almost like it has a miss.
I reset the computer while this is going on and the engine smooths out and it runs correctly until I keep my pedal down and then it kicks the exact same errors.
Here's strange part number one: Once I get down to about a gallon or two of gas in the car everything seems to run fine. I have plenty of power, no codes and the car runs fantastic!
Strange part number 2: Very occasionally When I get in the car in the morning to go to work, the car is a bit difficult to start. When it finally kicks over, it is immediately running rough. resetting the computer with the engine running does not seem to stop the rough running. If I turn off the engine and let the car set for a bit it will start and run fine, with the exception of the first problem mentioned in this thread. There is no code while it is running rough, but when the Light kicks on as per the first issue mentioned, I have an additional code -- 335. This car has been excellent up until the last few months when this issue developed.
Chevrolet - S-10 :: 1996 - Running A Bit Rough / Irregular Idle / Cylinder 1 Misfire
My 1996 S10 2.2 liter pickup has been having some 'issues'. Truck has been kind to me over the years, but now is running a bit rough. It has an irreguler idle and continues to run this way through all speeds. The blinking code reads "cylinder 1 misfire". I did all the basics. I changed the plugs and wires, ignition coils and fuel filter. Here is where is gets tricky, after changing the fuel filter, it ran great again. Then it started to run rough again later that day. I thought I somehow clogged up the new filter, so I removed the new one for inspection. Realizing there was nothing wrong with it, I reinstalled. Truck ran great again. Went out to drive it to work a couple hours later and it started fine, then after about 10 seconds of running, it went back to the rough idle.

So I have been unable to figure this problem out and so had my mechanic, I am starting to think this car is cursed. I have an 07 outback with about 54000 miles on it, a few weeks ago it through a P0303 for a misfire in the third cylinder, thought nothing of it, light went off in the next couple starts and the car was running great. Had this happen a couple more times but only after the car had been out in the rain. Each time the problem went away. Now the car has sat in my garage for four days, I got out to start it and get an extremely long crank but no turn over. Try again and after 5-6 seconds car turns over but is running really rough and stalls out. Disconnected the battery checked hoses, everything looked normal, reconnected the battery and now the car is running fine.

126000kms on 03 explorer 4.6 truck started. Running rough at idle and under load.... Code came up for cyl 8 injector. Replaced injector... problem still there. Switched cop and plug with another cyl and plug.... same code and cycl 8 is definitely not working. Would a generic problem always affect i cylinder. I even checked wire clip on for injector... it appears ok. There is power to injector wire clip.
View 5 RepliesAccent LC (2000-05) :: Cylinder Misfire / Rough Idle Then 2001 GS Dies
I've recently purchased an 01 accent GS and I've replaced the timing belt, water pump, and spark plugs. Ive also got no cold air, and original struts with 119k on the vehicle. Those are the least of my worries now as my car loves quitting out at idle; and it does not get any better hot or cold. One of the plugs was completely black when it was taken out (not by me: mechanic work) so that's when they mentioned a cylinder misfire. they wanted an additional 100 to figure out what that could be attributed to on top of the 550 for the work mentioned above! I am now next to broke and want to see if I can trouble shoot some of the causes myself. I am thinking Plug wires, crankshaft/camshaft position sensors (if there are 2 dif ones?) MAF sensor, o2 sensor, injectors, and fuel filter. My understanding is that the coil pack controls 2 cylinders at a time and I just have 1 bad cylinder...I need to figure out where to start as I have no codes to work off of. also, I don't know how to assess resistance with an ohm meter.

I recently bought a 00 Excursion v10 2wd everything looked right no major problems. I noticed it has a rough idle and i thought it could be the EGR i went under the hood and there's no EGR in sight. I plugged the OBD reader to see if it would give any codes since the there was no check engine light on and wanted wanted to make sure it worked, It showed a P0304 code its Cyl4 misfire i checked plugs/coils and i noticed there's a little insert inside Cyl4 plugs hole in the head that it has the plug screwed on. I decided to change all the plugs and the coils and i still have the rough idle and code i can hear a ticking noise around the engine in the passenger side.
View 7 RepliesAccent 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.

View 8 RepliesAccord :: 93 EX-R Running Rough And Engine Light On - 3rd Cylinder Not Firing
I started the car the other day and it was running really rough and engine light was on. I started pulling the spark plug wires and pulling #3 didn't make any difference in terms of decreasing performance where the others all did.
I've replaced the plug, and distributor cap. I've also confirmed with the plug out of the block that it is firing.
I'm not sure at this point what to look at next. This happened overnight, not gradually over time, and apart from running rough the engine isn't making any noises which based on sound, and how fast it happened doesn't make me think its a scoring/compression issue.
Golf IV / Jetta IV :: 2000 - Cylinder 2 Misfire And Engine Sputter
2000 GTI GLS 2.0L ... I understand I need to replace the Ignition Coil Pack on my car. I have looked on ECS Tuning to find the coil pack, but from all the pictures I see of other people coil packs they look nothing like what mine do. So I'm wondering if they are different for my specific car? So the issue that I have is my engine sputters sometimes, but more so when is wet outside. Its only cylinder 2 misfiring currently, and I replaced my Fuel Filter and Fuel Pump already in the past 4 or 5 months. Also a local shop had done some work recently and I know they had replaced the spark plugs. So I'm just wondering what coil packs I need for my car, and how I would go about replacing them. From what I saw online with other 2.0L (They weren't GTIs tho) was that the coild pack was behind the SIA pump or something like that, and they are a small black box. It looks to me that my coil packs are inline above the spark plugs and cylinders?
View 2 RepliesLumina :: 1990 3.1 L Engine Misfire When Cold - Running Rough
I have a 1990 3.1L, multiport fuel injection (NOT sequential FI), which runs very well most of the time. However, when I cold start it runs rough (misfire) for about 1 minute (no throttle) or until acclerated. The is no misfire when running normal, but it might be running a little rough when stopped at a traffic light (in Drive, foot on brake).
I put new plugs and wires on, but it did not affect this problem.
I am not using coolant, or oil, the plugs that were removed were somewhat worn, enough that I expected to notice a difference after they were changed.
I have not yet (1) cleaned the MAF, (2) checked carefully for vacuum leaks, (3) checked for leaking injectors.
Since this is a 1990, OBDI, I can't say which cylinder is misfiring or how the fuel trims look etc.
