put 99 si in 91 integra, new ecu, distributor both first gen. B16. new TP sensor, and map sensor, and fuel pump car still won't start. It is getting gas, and spark. what it would do is start sometime i would rev it and then all of a son loose rpms and eventually die. Then it wouldn't start. Also if it starts it is at like 300 rpms i leave the clutch pushed in it get to a 1000 i then press the gas to rev and it would drop and die out. What could be the problem please any suggestions?
