alright here we go... i have a 91 da Integra had a b18 in it. swapped for a B20b everything is running exact the fact that i have a demon. It idles high and hunting for steady idle. this Ghost idle is driving me insane... we have checked IAC, Vacuum lines(no leaks), throttle body, tried changing the computer from a 91 to a 92 but the plugs are different for some weird reason. i have a B20 computer but i need to cut every wire and go by on by one to hook them back up. dont want to get into that yet unless i have to.
needing some assistance with this nightmare please.

 

have you thought about getting a converstion harness would save you from having to cut the wires, and would allow u to test a newer year's ECU

 

try swapping another throttle body onto your Intake manifold it could be your map or tps sensor.

 

Ya I replaced the throttle body already and about the conversion harness where do I get that from? The intake manifold is different from a 91 to a 92 as well as the plugs for the ECU.
Running outa ideas lol

 

try 92-93 B18A PR4 OBD1
or 94-95 P75 OBD1 ECU

why would you use OBD2 B20B ECU?
get it done and install FPR set @ 48-50 PSI and it should be all good
