Ok people I know your probably tired of all my H22a questions, but that's what the forum is for right.....????? Any how here is the deal. I have a JDM H22a wired up with my F22b1 wireharness and using the OBD 2 to 1 harness with my Stock JDM P13 ECU. I also converted from auto to manual and I used the Stock Cat from my CL. I can not remember off the top of my head if the stock cat from the CL has 1 or 2 O2 sensors, or vice versa with the Prelude one. This could be triggering the engine light. Since the harnesses is OBD 2 and the motor and tranny are OBD 1, my mechanics code reader can not grab a valid code to tell us what is causing this light to go off. Does anyone have any insight on what to do or what instrument to use that could read the code? Lastly, The other day I started my car and I noticed the engine light was off, but my car was running like shit for like 30 seconds, it got so bad it basically felt like the car was running out of gas, then 20 seconds later the engine light came on and the car felt perfect? I believe there is some sensor that is responsible for the fuel mixture is defective or something and is possibly causing my car to do that. Any insight on this?
