91 Civic w/ b18a1 revs only to 3500
I have a 91 civic dx coverted to mpfi it had a d15 in it that ran fine and now i have put a b18a1 with a obd1 dizzy p75 ecu with jumper harness all stock internals. The problem im having is that it doesnt rev past 3500 rpms. I checked the cel and it doesnt throw and codes. The check engine light comes on when i dont jump it. As soon as i jump the plug with a paper clip the light goes off. Also my knock sensor isn't hooked up and i just replaced the tps sensor and i checked all my plugs and made sure they are in the right place. Any suggestions?
