Can any one help me out here. Stock 01 Raptor, starts to misfire under load. Once the problem starts it will only idle, just. It will sometimes cut out all together. Can not figure it to be ignition or fuel. Removed and cleaned carbs, air cleaner, fuel tank etc. Nothing found. Checked ignition system. Only thing found, running after market coil plug. Manual says it should have a 10k ohm resistance. This plug has 5k ohm. Does anyone know if this will effect ignition? Maybe it interferes with the CDI?
