Question

I have a 96 chevy, changed plugs, wires, distributor cap, rotor button and all 4 O2 sensors. Truck still doesnt want to run much til the truck gets warm. After it gets warm, it will run good. It will start fine, but when going down the road, it misses and doesnt want to run hardly at all. Its been scanned, and no faulty code at all. HELP!!

Answer

hello, Have you checked the fuel pressure? The fuel pressure should be 56- 62 with key on engine off and it should remain close to that after you turn the key off.
Thanks, John
