so i replaced the motor in my car this week when i cranked it the idle was a lil rough but the ecu had to adjust but when it got warm i gave it a lil gas adn then reved to 2500 rpm and then started to idle up and down from 2500 i have tried bout all i can think of i really need some help to fix this soon

 

Clean the tb and tps. It could be isc motor or FIAV valve. I have that problem with my dsm tb. I'll try to fix it tomorow.

 

ok man ill try it and see what it does if i can find these parts on the motor

 

It's on your tb. It's 80% your isc motor. I have one in perfect condition, tested. If you need it, let me know.

 

how much would it be

 

$50+shipping. I have the whole 4g94 tb. Problem with the idle can be caused by Fiav valve that located between tb and isc.

 

where exactly is the tps and isc motor and fiav valve located does any one have a diagram
