I need help figuring out some issues in my H22 CRX, I got the car already swapped, and I dont know much about H-series motors. When I got the car it was throwing 2 codes IACV and CYP. I fixed the CYP by wiring it sraight to the ECU. I couldnt figure out the IACV. Sometimes the cr wouldn't start unless I hotwired the fuel pump, then I could remove the wire, and it would start fine for a while, then same problem again. Then I threw an oxygen sensor and a fuel injector code. I reset the ecu and I just had the IACV code. I was driving one day and the car went into "limp mode". I reset the ECU and it was still in limp mode but wasn't throwing ANY codes. Now it wont start at all and its really frustrating because this is my only car.

 

wow... another daily driven H22 CRX. If you ever get rid of it i want it..i want it BAD.

but i have no clue what it could be. You should try asking in the make of car that the H22 comes out of about that.

Good luck
