I have a 97 chevy with brand new injectors and temp sensor,cap,rotor,plugs,plug wires. EGR valve. and new distributer, new fuel pump and filter. clean grounds. It seems to missfireing on 1 and 5 and it some time counts up on cylnder 2 but i believe it may be a false count. i have a new crank shaft position sensor but i didnt do a relearn. should i do that if so how. i need help. i am so confused on what the missfire is cause by. I will state it is some what new engine it has been fully rebuilt and built up. so i highly doubt its a intake gasket.
