Hi i'm new here, I drive a 91 Acura Integra LS with a 96 GSR swap using a PR3 B16 ECU OBD0. It was wired from one of my friends which i'm still using the LS distributor, wiring harness, starter, and alternater. My problem is my ECU is throwing code 4, 6, 22. I already know what the codes are, but all i want to know is why is my car not starting right. I have to push the gas down to turn it on then when i let it go it stalls out. I just need to know whats wrong with this problem please.
