Golf IV / Jetta IV :: 1995 - Random Multiple Cylinder Misfire?
Jan 8, 2014
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...

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?

I recently found these codes. My car is APR 1+. The car seems to run fine so I'm not sure what is going on. I changed the plugs at ~60K miles and now have 72K miles.

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 :
16684-random/multiple cylinder misfire detected
P0300-008- implausible signal

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.
- P0300: Random/Multiple Cylinder Misfire Detected.
- P0301: Cylinder 1 - Misfire Detected.
- P0302: Cylinder 2 - Misfire Detected.
- P0303: Cylinder 3 - Misfire Detected.
- P0304: Cylinder 4 - Misfire Detected.
- P0128: Coolant Thermostat (Coolant Temperature Below Thermostat Regulating Temperature).
- P0328: Knock Sensor 1 Circuit High Input.
- P0461: Fuel Level Sensor A Circuit Range/Performance.

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?

About a month ago my wife's 2000 Jetta with the VR6 engine in it started acting up and throwing codes. The codes it threw were for random misfire, misfire in cylinder 2, and misfire in cylinder 5. Starting out, we changed spark plugs, fuel filter, and made sure the injectors were clean.
The problem didn't go away so we water tested the coil and wires, but they passed that test. The wires were quite old and out of spec, while the coil was in-spec across all terminals, according to the vehicle service manual, so we installed some new OEM leads this weekend. While installing the leads we noticed a disconnected vacuum line and reconnected that as well.
The vehicle was driving great for two and a half days, then today while I was sitting at a stop light, it started missing really badly and felt like it was going to kill. It did this for about 5 seconds, then recovered and ran smooth for about 5 seconds, before getting really rough until I started driving when the light changed. It didn't do it when I drove it a few hours later at all. This episode didn't throw any codes either.
What could be causing this issue? Would the MAF cause the intermittent missing, or is it possible that the computer is going bad?

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

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.

It all started a few months ago.... I started my car, and it started noticeably misfiring, CEL flashing and everything. I scanned it with my vagcom and it came up Cylinder 1 Misfire and Random Multiple misfire. I popped the hood, made sure everything was seated correctly, and shrugged.
Ordered some new wires for it, since it had 80k miles on it with original wires, I figured why not. The misfire didn't come back.
A few weeks later, same thing happened. Misfires, flashing CEL, same codes. I ended up driving it the 5 minutes to work anyways and figured I'd look at it later after I got off.
8 hours later I started it up again, ran like a champ, no CEL on. The problem didn't come up again for 3-4 weeks.
So now, without fail, every month or so, I'll get the same issue. It doesn't matter if it's raining or sunny or cold or warm. But if I let it sit for a few hours, it'll act like it never happened.
Now, I haven't replaced the coil pack yet, simply because it doesn't sound like a coil problem, but I might do it just for the hell of it. New plugs and wires have already been done.

So I picked up this 24v vr6 in florida and it has the folowing codes:
p2181 malfunction in cooling system
p0303 misfire in cylinder 3
p0305 misfire in cylinder 5
p0300 random multiple misfires detected
p1570 engine control module disabled
I am thinking the ecu is fried? otherwise why else would that last code pop up. misfire codes im assuming are related to the ecu because theres new COP on each cylinder, newer starter, newer alternator, new spark plugs. Cooling system malfunction im thinking could be the ECT sensor, apparently the water pump was replaced a little while back.
If the ecu is fried can I buy a new one chipped from like APR or do they need the existing ecu and then they modify it?

I have a mk4 1.8t Gti. Recently I have been having issues with idle and boost. I read the codes and multiple random misfires in all 4 cylinders came up, idle control and the crank, knock, and o2 sensor came up. Shows that system is running to lean as well. I changed the spark plugs and wires, check the coil packs they where done about 1k miles so I expect them to be perfectly fine. When I clear the codes it idles below 9-8k rpms. I also noticed the breather hose coming out of the valve cover into the EGT has a hole melted into it, could this cause any of my issues?

The vehicle is a 2004 Jetta MK4 1.8t.
Last thing I had replaced about 2 months ago was the Solenoid valve, the MAF and Solenoid hose. Car ran fine for about a month, and bam...engine light came back on, along with the ASR light. At first it was saying "cat converter" so I researched that, and what a surprise, it spoke about being a $1k piece to replace. NOTHING HAS BEEN CHEAP ON THIS CAR, and I'm losing my mind.
The latest adventure happened today coming back from the gym. Car started jerking (which has been normal since every now and then the ASR light will come on, which I'm told is the traction control light. Causing the car to jerk. Simple fix is pulling over, shutting the car off, and turning it back on. That always clears it, and then I'm back on the road.) but instantly it lost power. It wont shift, but the traction control light didn't come on. I plugged my OBD2 tool up, and came back with these fault codes:
P0420: Catalyst System Efficiency Below Threshold (Bank 1)
P0753: Shift Solenoid "A" Electrical
P2637: Torque Management Feedback Signal A
I'm going to go to these guys tomorrow, but I would just like to get an educated guess on what might be going on, so I don't look like a lost dog while they're figuring out what to do next. These guys seem knowledgeable, but they're missing something since I've been in and out of their shop several times and still getting my traction control light on at random times, and now all 3 of these codes.
Does that Solenoid code have anything to do with the Solenoid valve they put in? I was told that cleaning the throttle body and the cat converter might work. Would those be cheaper options to consider, and see if that works?
I also read that unplugging the alternator and plugging it back in, then cleaning the male and female with electrical cleaner might work. I was told about a month ago that my battery barely passed. Could this be causing any of my issues? I also did a log while I was driving, but all that's showing up is a google map document.

I was running in a track day at Sebring today and missed a shift. Rookie move...the car eventually went into limp mode. I took the car back to the pits and scanned the codes. Limp mode was confirmed in addition to a cylinder 4 misfire and a random/intermittent misfire. Cleared the codes and went back out; couldn't even finish the lap before the car was thrown back into limp mode.
I was able to hobble home by keeping the car out of boost and started trouble shooting. So far I have ruled out spark plugs and coils. Should I be looking at the injector next? Any chance I bent a valve? The misfire can be triggered by putting the car under a load and bringing it up to 5,000 RPMs or higher.

I purchased a 2010 camry 4cyl. and i have this code of random multiple misfire, along with misfire on all 4 cyl. plus the P2716 code.
I had some issues with the fuel pump, got stuck, replaced it with a after market one, car did not run at all with it. So i decided to test the original one one more time. It worked, so i installed it back. The car starts just fine, takes off smooth, but when i get to 35-40 mph, the check engine light will blink, if i press the gas the engine will shake a little bit, and i can feel there is no power at the engine.
If i release the pedal for a moment and than press it again will run fine until i reach 35-40 mph. If it's in park, i pus the rpm up to 7k, engine runs just fine, no blinking check engine light, no engine shaking....
Like i said, 6 codes, 4 for each cylinder misfire, 1 for random multiple misfire, and p2716 solenoid....

I have a 01 wolfsburg jetta with aw engine code .. I have replaced and gaped spark plugs all 4 coils , DV. As well as fuel filter . Sometimes it runs fine . It misfire at random times most often at WOT. ..and I've noticed almost always when fuel level is low.. installed a boost gauge .. after disconnecting battery to reset ecu it boosts 10psi and runs strong .. however 1 or 2 WOT and it will misfire and then I won't boost over 4-5 PSI .. worst of all I get no CEL not even blinking .. I have also located a leak in the brake booster line . Does this affect it at all? ..

I have a 2000 Impala with a 3800 V6 series 2 with 165,000 miles. The only code I had was a P0300 Multiple random misfire that occured off and on at first, Worse in the city Better on Highway. It would start running on half the cylinders and bogged down, with the check engine light flashing, after getting onto the highway it would straighten itself out at first. I thought i had water in the gas so i ran some heat through it. straightened out for a day then happened again so I thought maybe a should run some premium gas in it, The car ran like total crap until the premium was gone, so i thought maybe it's running too rich, I put 87octane in it and it ran great for a day or two, then it gradually got worse to where it would not straighten up on the highway, tried to die at stoplights and i had to drive it with 2 feet to get it home and park it. I've replaced the battery, spark plugs, wires, ICM checked good, coil packs are good, replaced fuel Pressure regulator, looked for arcing on the spark plug heat shields and it will not start. It turns over but doesn't try to ignite and when I get the slightest rumble of ignition, it backfires up through the manifold and I see a puff of gas or light smoke by the exhaust manifold.
The car had a vacuum leak around the intake manifold cover gasket and a leak on the fuel rail. I pulled the fuel rail off my impala, snugged up the rest of the intake bolts then disassembled the fuel rail, flushed it out and cleaned the injectors the best i could, then reassembled it. before i re-installed the fuel rail I hooked it up to the fuel lines outside of the engine and tried to start the vehicle. all injectors had a nice spray pattern. So i installed the rail and it still didn't start but it had more combustion than before although it's still backfiring like before. Checked the fuel pressure by turning the key on and the fuel pressure went to zero very fast. I blew the rail out with air so to make sure i didn't damage the regulator I replaced it with the old one, ran the test again with same results, so i reinstalled the new regulator. I performed the fuel pressure test a few more times while moving the fuel hoses and when i moved the back supply line the vacuum loss stopped then dropped to zero when i let off of it. So I replaced the fuel line connector and O-rings on the injectors. It no longer has a vacuum leak.
I cleaned the EGR Valve out and had no luck there, then I removed the Idle Air Control Valve-pushed the pintle in, re-ionstalled it and WooHoo! it started! Although it still ran like crap with the same random misfire I was still happy to hear it start.I pulled the plugs on it to do a compression test and all 6 cylinders have between 180-190psi so the engine is in good condition mechanically. I installed new plugs before getting the car restarted and when i removed them for the test they were covered in thick black soot after running for roughly 15 minutes max.
I have (2) 2000 Chevy Impala's so I've swapped sensors from my wifes car to see if it would fix it. I've tested the following MAP, MAF, IAC, coil packs and ECM. None of these made the car change. I believe it is a timing chain because the car has never had a new timing chain and is way overdue, but I haven't had a code for a crankshaft position sensor. Can the timing chain be bad without throwing a code? It's not out of time enough to change the valve timing because I had a good compression test but its not firing right and still has the multiple random misfire. I have not checked or received a trouble code for o2 sensors, crankshaft position sensor or cam sensor. Something has the timing retarded and is dumping extra fuel into the engine because my new plugs looked like they were in the engine for a year.
