Golf IV / Jetta IV :: 2000 - Blinking CEL / Misfire / Oil On Spark Plug
Jun 17, 2015
2000 Jetta AEG ... An intermittent CEL light turned into a blinking CEL after a few months. Checked codes and it threw a P0303 (misfire on Cyl 3).
Pulled the plugs and found this:
There was oil dripping off of the plug from Cyl 3.
I last changed the plugs in July 2014 and only drove around 10k miles this past year.
When I changed them back then though Cly 3 looked like this:
Before I changed them back then I had an oil cooler gasket fail on the freeway and oil shot everywhere under my hood. Obviously oil is in there and it is causing problems.
I have read online and most of what I have read says that it's likely an issue with the VCG (Valve Cover Gasket) or the PCV (Pressure Control Valve) that is allowing oil to get to that part of the spark plug tube. I've also seen some non VW stuff talking about replacing the spark plug tubes.
Also it does appear that there is a little bit of oil around the threads of the other plugs but nothing getting to the all the way to the tip around the electrode.
I have pulled the plugs, wires and the ignition coil as well ... I'm ready for whatever. I am by no means a mechanic but I am capable of following instructions and doing what is needed. My problem is generally finding out what is needed to be fixed.

In order to replace the valve cover do the spark plugs have to be taken off ?

On my way to work, my check engine light started blinking and car was sputtering (real bad on idle). I ran the code and it came back with misfires codes. I changed the coils/plugs, fuel filter and fuel pump last year. Can the coils be bad already? When I clear the codes the car will run fine for a little while. But after a couple miles CEL will blink and the car will run roughly again.
Car : 2004 Golf 2.0
Codes:
16684: random multiple misfires
16648: fuel injector #2 short to ground

So last Thursday I started my car up in the blistering cold and it ran fine for about a minute and started to misfire so I shut it off. It hasn't ran since. When that happened the check engine light was blinking because of the misfire. I didn't have a code reader at the time to read it. now that I got a code reader the damn thing isn't throwing any codes. it spits and sputters sometimes. I've had no previous problems with the car. Thinking It might be a weak fuel pump or bad coils and in not sure how to test them.

I have a 2000 Jetta 2.8 VR6 (the 6-cyl) with 128k miles and I have oil on my spark plugs, only on one bank of the motor (the bank closest to the bumper, if that makes any difference). I am aware that it is most likely a leaking or worn out valve cover gasket, and I have a replacement and am prepared to replace it. What I need to know, and I can't find this exact part anywhere, is do I also need to replace the spark plug tube seals??? The gasket I ordered did not come with any tube seals, I can't find this part on any auto parts website at all, nor have I been able to locate anything useful on this, or any other, website. I know the 1.8 has plug tube seals, and they come with the gasket, but does the 2.8 also require tube seals? I imagine it would, but I just don't know.

Getting error code p0302, misfire in 2, pulled the plug and had oil on the treads and on the lower part. My guess is the valve cover gasket, but I'm not 100 percent sure.

I am getting a cylinder 5 misfire and this has been a "on again off again" situation since last August. I took it around to a few places and the general solution was to get new spark plugs. After doing a bit more research I was advised to change the coil cover. I did that and it fixed the problem. Then about 4 months later the light came on again. I happened to change the air filter and the light went off. I though great, problem solved! not so much, when i went to the mountains the other day the light came back on. I did my research again and I have decided to get the plugs changed. Its a 2005 f150 with 94,500 miles on it.
I am told its time to change them regardless. I started calling around and getting quotes and have been told by multiple shops that ford made the plugs in my truck in a bad way. They have been telling me to change them and breaking them is a 50/50 shot. THEN, when they quote me they charge a rate to replace them plus the plugs themself. If they happen to break one then the customer pays for the new one. Do the plugs would really break that easy and should I plan on replacing some of them?

I have a 2006 F250 5.4L. I was getting a noticeable misfire after not driving the truck for a while. Mode 6 revealed that cylinder #8 was misfiring.
I took off the coil/boot and there was coolant on the tip of the boot and some at the bottom of the spark plug well.
I cleaned everything up and put everything back together and that took care of that problem when I started the car. I also stuck a wad of paper towel by the intake manifold nearest spark plug number 8 and tightened the manifold bolts down a little. Some of them were not as tight as others.
I went back today and started the vehicle and it has the same problem again!
I took a look at the paper towel and it was totally dry! There is no coolant around the top of the spark plug well - only in the bottom of it. Where is this coolant even coming from? There are no coolant lines near cylinder #8. Is this a head gasket leak?
I have taken a look at the head gasket and that doesn't seem possible since the head gasket does not seal around the spark plug well at all as far as I can tell.

I have a volkswagen jetta glx vr6.Today my key wont turn (unable to crank engine) and the car won't detect my key (no remote entry/lock function).I've detached the battery.
Plugging the batter back and keeping the key in:
1. Off position causes the "Electronic Immobilzer" light to blink.
2. When in on position. no "electronic immoblizer light comes on.
3. In anycase I can't get the ignition to work.
My engine check/airbag lights are also on and my radio/ac doesn't work. Also the electronic controls for rear view mirrors don't work. Half of the tail (exaust) pipe rusted and has fallen off.On the funny sideI asked the guy at VW to appraise my jetta for a trade and he said it would be $500 for the car !! ONLY After the company official tested the car this won't start...the sales person left, since it was 6PM on Friday. I was left alone and had no option other than to leave my car at Pugi VW showroom and ask a friend for a ride...Long story.

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?

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?

I bought a 2000 lincoln LS from my father-in-law knowing it had some issues. We were incorrectly told that it needed cam shaft sensors, but I had it checked out myself today.
4 (out of 8) cylinders are misfiring. He opened it up and saw that on the right bank 1 of the spark plug wells was filled with oil, and the other 3 the tubes are seeping. He also said 3 of the coils need replaced. Whoever had the car originally replaced 3 coils (they're 3 different part numbers on the coils they used).
I've been researching and the first suggestion is changing the valve cover gaskets and removing the oil to see what problems if any it eliminates.

2000 Excursion with the 5.4 in her. Lots of miles. Used only to tow a travel trailer. Blew out the #3 coil packet and spark plug today. Have to pull the head for sure. My question is why? Is there a more severe problem as to why it did this? Or is my old girl just worn out. 270,000 miles.

My 2000 vr6 gti been starting too act up. After about an hour or so of driving the ride gets rough , loses power and it makes this knocking noise . Although when I punch the clutch in the knocking goes away . Besides the knocking going away the rides still pretty rough though . Once it starts this it starts too backfire way louder than it usually does and it throws out this funky smell kind of like burning oil /syrup smell lol .
I really wanna fix the car . When the car does drive good it's no complaints at all . I do know that I have a misfire in cylinder 3 & 4 though and I do have all the codes scanned from the obd2. I've heared of this being the throw out bearing but I'm not completely sure. There's a video to actually hear it. [URL] ....
Obd2 Codes :
P1473
P1432
P0300
P0301
P0306

My daughter's 2000 Jetta with a 2L has an engine light and codes that state Misfire on 1 and 4. It is intermittent as it only misfires once in a while.. She is in Rolla MO, and I am in Detroit MI. A couple of years ago the car died when she was home and I found a swollen/cracked coil pack. I replaced it with an aftermarket. The plugs and wires were replaced about 30k ago with OEM parts. I am tempted to have the son in-law replace the coil pack with a Bosch unit.

I bought a 2000 excursion a month ago and have already had 3 plugs blow out on me. They've been repaired professionally with time sert but the mechanic is starting to wonder if back pressure is building up causing this. He's suggesting to replace the catalytic converter as it's original and has 120,000 miles on it. He's made it clear that he doesn't know if this is the cause but to lose 3 in a month worries him. Is there anything else I can do?

I recently became the owner of a 2000 Ford Excursion V10 (limited) with lots of extras (5.5 inch lift, dual exhaust, 37 inch tires, a 2005 front end, etc).
The intent is to use the excursion as my winter driver, towing vehicle and people hauler (things my 2010 mustang is terrible at). Unfortunately, my 5th time ever driving it, I was pulling out of my driveway and accelerating when the engine blew a spark plug. Since I do not have the tools to install a helicoil, I have taken it to the local shop to get repaired.
I am now concerned about the remaining plugs, and the general reliability of the motor. It has ~200,000 miles on it, and multiple previous owners. I have no way of knowing what work was done on it in the past. I did check all of the fluids when I first got it to ensure they where still good, but are there any other common issues with these V10's that I should check? Can I do anything to prevent any further spark plug blow outs in the future?

So, I have a 2000 Hyundai Accent that has had the CEL light on ever since I have owned it (about 7 months). I was told it was the O2 sensor and did not have it scanned. Occasionally, it would lose power and the CEL would blink. After I would take my foot off of the pedal and baby it for a sec it would usually go solid again and drive okay. About 2 weeks ago it started blinking constantly and it sputters and drives like sh*t. Now, I know that I should take it to Autozone or someplace so that they can tell me which cylinder is misfiring and all, but it is really sketchy to drive. I put NGK spark plugs in it today with no change. I ordered plug wires and a coil pack to see if that straightens out the problem. If it doesn't then I am going to lean towards intake gasket or perhaps a missing or bad o-ring at an injector. So, does this sound like a reasonable plan of attack to get rid of the blinking CEL (misfire) and restore my Accent back to all of its craptastic glory?
