If you are saying your engine is missing bad, it is probably not a fuse. Do you show any Check Engine lights? Have you had the car scanned for codes to help trouble shoot? What engine are you running and is it fuel injected? When was the last time the car had a tune up, Plugs & plug wires changed, dist cap? rotor? etc. Do some digging with more info to help us help you. This sounds like an ignition problem.
