hmmm....now i have another problem. in between the "warm-up" the engine revs up and down. then the idle drops all the way to 300rpms...it's literally 300rpms.
then it'll either die or shoot up to a 1000rpms.

also what i had noticed is when the engine is cold and you remove the tps harness; the idle goes down to normal?

it's as if the tps is fast idle control or something.
