I have a friend with a 2.0 jetta and it feels like its going to stall out soon after starting and its pretty rough while accelerating lots of misfiring. I am assuming its the MAF. but does anyone have any other suggestions on what it could be?

 

ok I went and drove the car earlier today and it doesnt accelerate. when you press on the gas it just kinda rolls at a tiny bit above idle speed. any suggestions?

 

could be a lot of things. has he done general maintenance items fuel filter, plugs.... Has it progressively gotten worse, or was it a night and day change for the worse?

 

Check Coilpack if Mk4 (I think the MK4 switched to coil), or Distributor if MK3. Could also be fuel system related.

 

its a mk4. im not sure if it was a progressive problem or not. I dont really talk to her very often she just called me out of no where.

 

Also could be a vacuum leak.

Is the CEL on?

 

yea the CEL was on.

Any one local to you have a vag-com? Scan it and see what the faults are.

 

yea I was calling around earlier in the day to see if anyone had one. I ended up calling a euro mechanic and he was like "yea bring it on in, it should only take a minute and its about $250" so yea, I wasent about to have her pay 250 just to run a vag com on it.

 

Go to Advanced Autoparts first and have them run the code and then just get an idea of what is going on. Also if it is a code they don't know, post it on vwvortex and someone can look it up in their Bentley.
