Here is my problem. My check engine light keep come on for map sensor ( 3 blink ) after I swap a 96 B18 into my 93 del sol S. It's funny cause the del sol have a map sensor mounted to the fire wall already. But the engine it self already have a map sensor on top of the throttle body n plus the engine harness already have a plug for it too. when I use the plug from the fire wall than the check engine light gone but idle really low n seem like it's gonna cut off the engine, plus it don't feel right when I'm driving. It just suck gas but car wouldn't move like it suppose to. On the other hand when I use the engine harness plug it run right but check engine like come on. During driving in between shifting gear if you don't step on gas than the engine cut off. Some time at the stop light the RPM just drop to 0 n begin to die out. This ECU wan run in a turbo hatch before n not sure he that dude done some modification or not. It's a P75 from 94 model. So I'm running an OBD-1 ECU to an OBD-2 engine which I think it should work and I've recorrected my self on the wiring soo it should be that problem. Any B series fanatic out there care to help me?
