I have a 97 prelude that I had to put an engine in. I bought a jdm h22 that is a 95 and had to use a jumper harness to bypass the cam and crank sensors used on the 97. I guess engine is obd1 and ecu is obd2. Engine starts but doesn't run good under load and tach is bouncing all over. Does distributor need to be re - wired or do I need to change ecu or any other suggestions??
