I have a 90 Jetta. 1.8 digi. recently installed a new fuel pressure regulater.. and the car ran as it should.. now .. it spudders horribly and Black smoke (fuel problem).. any ideas of what to check?
I have changed.. mass meter, idle air stab, fuel pres reg.
Thanks,
Mitch

check the lines and make sure they are on all the way. i had this really bad smell of gas in my car for a while, and so finally one day, i went out to my car, started it and put up my hood, and my fuel line wasnt on all the way. it was like putting out 1 drop like every 1 second but still. check those. it might not be it, but it could help. sry i cant help beyond that man. hope it all works out!

Hey vwgoner .. thanks for the info.. I figured out the prob though, It was the Air Mass Meter, the temp checker in it.
