2001 jetta check engine light-cylinder misfire code
Had my jetta for about 6 months now,has always ran fine.Today I drove to work,went to lunch and it drove like normal.After work she fell on her face when I PULLED OUT ON TO THE HIGHWAY.The engine check light came on and she was underpowered and accelerating rough.I went straight to Autozone and had them check the codes:cylinder misfiring...................bad gas,plugs,????I put some heet gas dryer in and some more fuel,plus some fuel inj. cleaner.If this does not help,plugs next?Or what next?Only jetta I ever had so help.It is the 1.8 turbo gas.

Probably something in the ignition. Start with the easy solution the spark plugs and let me know if that doesn't work.
|
What is recommended?NGK Platinum
|
If you want the longest lasting get Bosch irridium +4's (pricey). For performance get Bosch platinum +4's (I have those in my car).
|
Thanks will see what I can find.
|
What about an NGK iridium plug?
|
If you want to put Japanese plugs in your German car go for it. They should do fine.
|
ooops!
|
I was just kidding.
|
I put in the plugs,went smooth.Still runs rough but not as bad.Check engine light came back on.Next?help?
|
Does the code need to be reset before I would really know if the plugs helped?
|
What did the old plugs look like? Were they bent, melted, black or white? Or brownish or grey (normal).
|
From the passenger side:#1 #2 were white #3 looked normal #4 white.They were autolite platinum.
|
Three of the coils appear to be original(vw/audi)on them.One looks to have been replaced(looks new/vwak).
Change coils next I guess. |
Ran the code again p0303-cylinder 3 misfire.Will replace one coil at that cylinder.
|
coil fixed it.
|
Nice work.
