iight i have a JDM b16a swap in my 96 hatchback, and i when i first start the car it idles at 1,500 RPM and then in like 3 min it starts to go up to 3,000rpm, ok i turn off the car then start it up again and it idles at 1,000rpm, ok so i turn off the car then i start it up again and it finally idles at 750rpm but if i start the car on the 6th time it idles at about 450rpm and feels like it is suffercating and will evenually die out, but will start right back up and idle perfectly. and the v-tec comes on at about 5,000rpm,

USDM ECU GSR p.72, i had the jap oil pump senor and all that other stuff replaced with usdm so i can pass emissions and no check engine light, the perfessonal mechanic who did the usdm ECU convertion said all the wiring and stuff is perfect, but i guess he over looked the idleing problem,
need some advice or help please

 

First off get the right ecu, 2nd off maybe ur IAC is taken a ****?
