Montana | My spray truck is a GMC Topkick 1991 and it has throttle body fuel injection, It runs a bit rough and I believe there are some key parts that we could and should replace to make it run great. I see Throttle body injector and fuel filter as well as Idle Air Control Valve. Is there a very good High output coil that would help the performance of this truck.
We replaced spark plug wires and cleaned the plugs yesterday. the high performance, silicone wires, are supposed to withstand extreme heat and they would not fit in the metal sleeves. Will I have problems if the plug wires are not shielded by the metal covers? | |
