So the swap's been done for a while but the car is running like shit. Once it's warmed up it runs good...not like it should however. But first things first, when I start it, it tries to die...so I give it gas and have to pump it to keep the revs up. If I hold my foot on the throttle...say to about 4k...it'll drop down and then come back up...until it's warmed up...then it stays at 4k where it should. The car is obd2 and the engine and ecu are obd1. Used a conv. harness but do I still need to switch pins a6 and a11? If anyone can help I'd appreciate it. And if you need more info let me know. This shit is driving me nuts...as I have no experience with this shit and it's been my first big project. Thanks guys! ps - i checked and replaced the tps sensor so I don't think that's the problem.
