I have a 1996 Acura Integra swapped with a 94 GSR. With an OBD1 ECU I am throwing up code 4, code 6, and code 22. With an OBD2a ecu I am throwing up code 54. My car is not drivable and at idle it revs from six to nine hundred back and forth and when you give it gas it dies after 2500 rpms. What is going on?

Thanks

 

ecu crapped out? my homeboy has the exact same thing and his obd2 works on it fine, and the obd1 does too. if you are throwin random mixmatched codes on both ecu's it could also be wiring
