i have a 88 vert with a 89 intake with brand new injectors,full racing beat exhaust,and a k&n air filter i just got it back and the idle is rough and i have to floor the gas to get it to start the guy tried adjusting the TPS but said it wouldnt adjust out i never had any problems with it before the mods but hee said it was because my timing was so advanced, is this true? it doesnt have the usual symptons of a tps like jumping from 700to1500 it just idles rough and has like a fuel miss is there any way i can test the tps with a ohm meter? and how would i go about doing it? the car pulls a wole lot better since the mods but im not happy with the idle i dont like to push in the clutch and turn a corner and the car cuts off,not fun any help would be appreciated im going to try and swap out the afm and see if that helps i have an air fuel guage and it does show that it is running lean thanks,Dave

 

Which TPS are you using??? The 88 or the 89????? On the 88 car??????

 

im using the 88 i ordered a new one but i still dont see a adjustment on the TPS what would it run like if i just put a new one on would it still need adjustment due to the mods?

 

I think you may need the 89 TPS. I'm not too sure, I don't get to mess with S5 cars much

 

i have the 89 intake but i have to use the throttle boddy from a 88 the car runs fine when im running it its just when idles the car sometimes wants to cut off when i turn corners and idles basically where it wants to sometimes 750 sometimes 1500 just depends on its mood i guess i ordered a new TPS for a 88 but was wondering wheres the adjustment and if i would have to adjust it due to my mods?
