Dave_McC 0 Posted December 30, 2007 Hi all Car is a 1990 1600 Gti and is currently standard. Starts on the button and cold idle works fine. However, on light(ish) throttle openings, the car constantly feels like it's misfiring - this isn't the no throttle jerkiness 205's are notorious for. When you put your foot down, engine runs cleanly and smoothly right up to the red line. I've also noticed recently that sometimes after stopping when the engine's up to temp, if I restart it within 10 mins or so, the symptoms are even worse - to the point it sometimes refuses to idle. Any ideas where to start? Cheers Dave Share this post Link to post Share on other sites
simonb 0 Posted December 30, 2007 (edited) I would look at the afm - may need retracking, and then the TPS. Try unplugging the TPS from the throttle body and see if you get the same problem and the given RPM. Edited December 30, 2007 by simonb Share this post Link to post Share on other sites
DamirGTI 342 Posted December 30, 2007 Hello ! I've had similar problem and i fix that with adjusting the air/fuel mixture and ignition timing .. Try to adjust the ignition timing , advance it a little bit and see if that helps (if it's not a Motronic engine management ..).. is the vacuum capsule on the dizzy in good condition , dizzy to TB pipe connected ? As said it could well be the AFM , or TPS ... Cheers ! Damir Share this post Link to post Share on other sites
