Re: How To Adjust The TPS And IAC
There is a detailed procedure somewhere on this website. Personally, I searched for it, followed the instructions exactly, and now the car idles like a kitten and has sharp throttle response. IAC is adjusted by the ECM, but minimum idle and TPS are adjustable.
I don't remember where the info is though, sorry.
