I've been chasing this problem for awhile now. I have a 95 LS, with a 16A2 head on it, ran by a jdm p30 ecu.

What happens is this. When I first start the car, it idles at about 1200rpm. After the car warms up, it idle gos up to betwen 1800 to 2100 rpm. It seems to be constant idle at X rpm once it has chosen a value to idle at. This however is subject to change within that range on various starts. It seems to have to do with outside air temperature. colder= higher. However, its odd to me that on initial start up it seems to be within the normal cold idle range.

Any thoughts?

Thanks,

Mike
 
try looking for a vaccume leak (maybe your iac is out of adjustment, maybe if u had ur TB ported, it could have been messed up) but to look for normal vaccum leaks just take a piece of vaccum tubing and put one end to ur ear and one end to you possible leak spots. ull know when its a leak
 
check the IACV i had that with my swap fixed the wires and i was good
