i have a 96 civic hatch with a d16y7 and it has a problem with a pulsating idle. i tryed changeing the iacv and the wiring harness and still no luck…come to find out my ecu which is a p2e ao1 is not sending any ground what so ever to my iacv so if anyone knows where i can get one of these ecus it would be much appreciated
have ya checked the coolant lately , i say that cause they do that if its low or air in the system.if ya had no ground the car wouldnt idle at all or it would be fixed not up and down
the coolant looks alright and it idles up and down when i start it but when i run a jumper wire from the ground on the iac to the ground on the battery it idles perfectly
i have an auto P2e ECU out of my 00 sedan. You’d need a jumper harness tho…
