I have a '06 Passat 3.6. I had the intake and valve cover off the other day and when I put it back together it started missing bad. The code it is throwing is a P0300/ random/multiple engine cylinder misfire. What is wrong?
View 2 RepliesPassat (B5) :: Error Code 16684 And 16686 - Random / Multiple Cylinder Misfire
I was driving along and the engine started missing really bad. The whole car was bouncing around. At first I thought I had a flat, but when I stopped I noticed it was the engine. I checked the error codes and got 16684 and 16686 --- Random/Multiple Cylinder Misfire.
I had a problem recently with the vacuum hose broken and was causing an error code. Replace the hoses and it has been fine. Checked to make sure that the hoses were secure and they are fine. Doesn't seem to me to be related. So many problems for a car with 57,500 miles
Accent MC (2006-11) :: Multiple Cylinder Misfire
My car has been really acting up lately (AGAIN) so I took it in to have it looked at and they came back and told me it had multiple cylinder misfire, and they wanted like $1200 to fix it. What in the world does that mean and what is entailed in fixing it? They mentioned doing a full maintenance on it.

Replaced my water pump March 2nd using the "From Below" method. Started the car after and the check engine light was on and water pump was no longer leaking. I drove the GTI to Advance (15 Mins away) it drove fine and I pulled two codes.
P0300 - Random Multiple/Cylinder Misfire
P0301 - Cylinder 1 Misfire
The car pulled and drove normally. The next day the car is misfiring badly. Hesitation and bucks when accelerating until roughly 3k then smooths out.
I will swap my coilpacks and check if the misfire moves as soon as I can get my hands on an OBD2 Scan Tool.
From what I understand about the VR6 :
-The water pump runs off the serpentine belt
-Camshaft timing is controlled by the timing chain.
-Timing chain is not affected by the serpentine belt/pulleys.
Questions :
-Can turning the Crankshaft Pulley affect timing?
-Can that be the cause of the misfire?

We bought the car used for my youngest daughter and it had a couple of codes in it. 1st was the o2 sensor.. easy fix, grabbed an OEM one and stuck it in. Then there was the Cyl 2/ multiple cyl misfire codes that kept getting thrown.
I've seen a bunch of post about people pretty much doing the same things I started out with and still having a problem.....
1) Swapped around all the coils.. still got a #2 misfire... So, coils are good.
2) Swapped in NGK Platinum plugs with a .032 gap.... still getting misfire.
3) Replaced the crank shaft position sensor...... still misfire
4) Noticed that there was an Ebay injector in the #2 cyl...... when I pulled the plugs, that cyl was running a little lean..... bought an OEM injector to go back in there...... still getting misfire
SO, I tried using a propane torch head and putting out gas around the intake to search for vacuum leak and got no response....... so, for the heck of it, I went old school and grabbed a can of starting fluid and started spraying it on the intake around where it bolts to head... bam... found a vacuum leak on #2 cyl....... ordered an intake gasket off of ebay, spent about 3 hours on it pulling the intake and replacing the gasket,( the bolts had loosened up over time and there were small tears in the gasket allowing it to suck air) .. put the new gasket on, cleared the codes and it's been running perfect ever since.
Check for a vacuum leak where the intake manifold bolts to the head... might save time and money.

I guess misfires are a rite of passage for these vehicles. I purchased it only a week ago. Welcome to Hyundai...
The car has 53k kms. It's throwing P0300 and P030X on all cylinders. There was one instance of P0128. The engine runs smoothly and doesn't seem to down on power, although I have nothing to compare it to. The only performance issue is that it acts as if there is a rev limiter at 6k rpm. It sputters and stops pulling above 6k. Strangely, it doesn't throw the codes under load. The light flashes while it's running steady-state.
I pulled the plugs and they appeared to be in excellent condition with no erosion of the electrodes. The ash is slightly more white than I would expect, making me wonder about it being excessively lean. I called the dealer. They told me that coils are problematic. Replacing the coils made no difference.
That lead me here. I found the thread "Check engine light flashes then stays solid," which referenced the ECM update.
Interestingly, of the codes mentioned on the TSB, the car is having all but the last two.

Golf IV / Jetta IV :: 1995 - Random Multiple Cylinder Misfire?
I have a 1999.5 Jetta VR6 12v, last week the car would not start. After some tests I determined the coil pack had gone bad. Replaced the Coil with a brand New aftermarket German made coil. Now 1 week later, driving at highway speed CEL came on, started to flash and obviously misfiring again. Ran Codes and now im getting these DTC's:
1)random multiple cylinder misfire detected p0300
2) cylinder 4 misfire detected p0304
3) ignition coil output 3 electric malfunction p1395
4) cylinder 3 misfire detected p0303
has this new coil gone bad already after a week?
New issue?
Plugs were replaced less than a year ago, wires were apparently replaced by previous owner about 2 years ago now. Crank sensor replaced less than a week ago...

1996 Blazer - Flashing Cel Light P300 Multiple Cylinder Misfire?
So my 96 blazers cel started flashing and the truck started running extremely rough. I changed the catalytic converter and the o2 sensor that is in the pipe. Made no difference. So I knew my intake manifold gasket has a leak so I changed the gaskets and put knew bolts in. I wasn't thinking and took my distributor out and forgot to mark the timing. So played like heck getting it in timing again. Took a bit cause I didn't realize there was two timing marks. So got it started again was running really rough so thought 180 off turned it nothing. So put it back started it up still running very rough and flashing cel so put a new crank sensor and cam sensor in and a ignition coil in. No dif still. Could it be the egr or ECM?

Golf IV R32 :: CEL Start To Blink Then Stay On - Random / Multiple Cylinder Misfire Detected
I was driving the car normal with no problem. Got to a red light stop an as I was coming out of the red light the car started to hesitate a bit. So I start to drive home as I was driving home my check engine start to blink and then it stay on. When I got home and park the car I shut off ,then start it up again then the check engine light was off but the hesitation was still there. Then I got my computer and got the vagcom and got this code :

Buick - Lacrosse :: Oil Pressure Low Light Came On - Random / Multiple Cylinder Misfire Detected
2008 Buick Lacrosse CXL .. My son said the Oil pressure low light came on when he tried to start the car. It didn't want to start.
When I got there two hours later, it started but had a check engine light. But no low oil pressure light. Sounded like it was missing.
Code from computer came back P0300 "Random/Multiple Cylinder Misfire Detected". I cleared the code. Revved the engine to about 2000 RPM's and the CEL came back on.
Same code. When idling it feels like it's missing. The plugs look good, I am going to replace the ICM.
Jeep - Liberty :: Idling Rough With No Error Codes - Multiple Cylinder Misfire
ODB2 Code: P0300 - Multiple Miss-fire
I have an issue with my Jeep Liberty. It started idling rough with no error codes. about a week later it through the Multiple misfire code. I started by replacing the spark plugs. The old ones were from 20K miles ago and still looked good. Replaced them anyway. I still had the code. I put K44 fuel injector cleaner into the tank and drove it home (2 miles.) The next morning I started it and went in side because I had forgotten something. I came out to extremely thick black smoke. It went away after about 2 minutes, the computer code cleared, and the engine idled perfectly. About 2000 miles later the car is once again idling poorly. I added K44 again and for that tank of gas it ran fine, no code. Once new gas was added it threw the same error code and idles very roughly.
So here are some basic info pieces:
1. 8 tanks of gas from 8 different locations.
2. Adding K44 has shown a direct improvement both times, but more significant the 1st time.
3. New spark plugs
4. New coil packs
5. 2005 Jeep Liberty - 3.7L V6 at 99,872 miles
6. Hopefully unrelated is that the car has a small radiator fluid leak I haven't found. It requires 1/2 gallon every 2K miles or so.
There is no knocking sound, it just sounds like there isn't enough gas. Car responds fine to accelerator. Above 10mph car seems to drive smoothly.

Ford Super Duty (1999-2016) :: 2008 F350 - Multiple Codes / Cylinder 5 Misfire
My dads truck started misfiring last week, first thing i did was scan the codes and got p0303, p0304, p0305, p0306, and p0308. Its an 08 F-350 5.4...already changed out the spark plugs and the same codes came back. I decided to do some further testing and so far all coils had spark as well as 12.4 volts going to each. I did check the switching signal and that was present as well.
Moved on to the injectors and i checked each connector with my noid lights and it flashed on all cylinders. Did a resistance check on each injector and they all registered 12.4 ohms. We did switch some coils around and all the same cylinders misfire. My next step is to do a compression test.
My biggest question is if there are any common problems with these engines besides the coils, by the way this truck has the brown coil boots and the spark plugs that dont break in the engine.
Ford F-150 (2004-2008) :: Cylinder 8 Misfire Code Randomly
Having a misfire problem I can't track down. First issue was random cylinder 8 misfire code. Checked everything, nothing obvious. Cleared code, problem stopped and engine ran fine. Then came back, cylinder 8 misfire. Swapped coil with #5 but problem did not return. Since I assumed it would come back, I went ahead and bought Accell supercoils and new Motorcraft plugs and replaced them all (120k miles, no broken plugs ). Truck ran great on the test drive! Then it sits overnight and bam, cylinder 5 misfire as soon as I start it next morning. Then after messing with it I get cylinder 5 bad coil (code 355 I think). Put one of the Ford factory coils back back on #5, no change and still misfiring. New plug, new coil on all cylinders... Why did it move from #8 to #5? If it was an in injector, seems it would still be #8 since I did not mess with those.
