Hi , my car is like new and my idle is low around 500rpms, when warm it almost feels like it is going to stall....it there anyway I can increase the idle speed without bringing it to a dealer? I do most of the work myself on this car as im pretty educated on the basic stuff....Does it need to go to the Computer Dia. machine? is there a adj. Valve? or could it be the Idle control valve? ive checked the massairflow censor and cleaned it just so you know and it has been given a tune up.....thank for your help, Max

The software at the dealer is the only method I know of to increase the idle speed.
