Hey guys, I have a '94 Z A4. It has 57K miles. All stock except hooker cat-back. Car was running fine 'til tonight. I got in it, it started perfect. When I came to the first stop light, the car started to stumble or buck, not sure how to describe it (the engine was shaking the car). When I put the car in neutral, it clears up. I did notice the exhaust smelled pretty bad. I didn't get an SES light so I don't know what is wrong. I didn't get a chance to really get on it but it seems to run ok other than when first coming to a stop. Any ideas? Anything I should look for? You guys are awesome. I know I can always find great help here.

 

Might be the water pump going bad,and leaking down onto the distributor(opti).My02

 

whens the last time the car had a basic tuneup? check the coil

 

whats this damn coil im reading about does anyone have a picture so i know what i am looking to clean my car does the same damn thing, runs fine then the ses light flashes,

 

whats the code yr getting?

 

i dont know havent got it check, I know what the deal is Im sure its the opti or so because it rained like hell for a whole day and drive home after work fine lots of puddles but next day went nuts and freaked out

 

well get it scanned at autozone they do it for free, that can be a start, just do the basic's, plugs, wires, fuel filter, check yr coil, could be bad or a bad connect, just pull the wire off and look to see if its dirty, wipe it clean and see what happens, if you do all the basic tuneups and yr still having a problem it most likey the opti
