Okay, I'm new to the swap scene and I have a question.. I bought a 1990 integra rs with a b20b motor. When I purchased the car the car was running good very good. Now the car doesn't run. It will turn over but will soon shut off unless I tap the gas but even then it will only help a little.. I can't floor it either, it'll only go to 3000 rpm. I've changed fuel pump fuel filter plugs wires, I'm thinking it could be tp sensor or maybe crankshaft speed sensor. I don't wanna put more money into and it not solve any problems. Any help would be greatly appreciated
