The fuel cut out at 4500 rpm and the shit is a real pain in the ass. The wierd thing is that it only does it when i am running my obd1 p72, but when i am running the piece of shit obd2 p28 it doesn't do that, what can be my problem. Also it throws different codes when i have the p72 in then the codes that the p28 throws. I think it might be the jumper harness or a wiring problem in the main harness but holy shit this shit is really a big pain in the ass.
