i'm hoping someone can help here finally... i have a 95 coupe and when i start the car after its been sitting the idle is all messed up and the rpms are jumping from 1 to like 2.. 2 and half and the **** does not stop until the car finally warms up after driving for like 5 mins sometimes longer especially when its cold.. ive already changed the tps sensor cleaned the throttle body and everything else i've been told by friends and it still keeps doing it.. does anyone have any idea how to fix this?? everyone tells me its common but it im tired of it lol
