i have a 89 t2 and the car doesn't idle, i set the tps to 1kohms still the same problem. The car doesn't idle at all or it barely stays alive. if i rev it to about 2000rpms the car will run at that speed for like 5 seconds then it will bounce from 1500-2000rpms car doesn't bounce past 4krpm just low end
i'm thinking that its a vaccum leak or something, any suggestions?

 

ckeck to make sure the AFM is working properly, check for leaks etc, check injectors and make sure thay aernt cracked and whatnot, and search!
