Just did the y8 swap back in my 98 ex. It starts up just fine but has an idle problem. It surges up and down really fast. It has the IAC code 14. I'm using the P2P ECU and I also have an OBD2 P72 I've been trying to see if it runs any better. I noticed it's a complete y8 swap with obd2 wiring harness but the Intake manifold and injectors are all OBD1 I had to change the injector clips over. Could this be a problem. This is a pic of 1 coolant line coming from the OBD1 intake manifold that I just plugged up because I couldn't find where it went.
