Why does your truck run rough after changing the distributor cap and rotor?

Rough Engine Performance AFTER Changing Distributor Cap and RotorThe only thing I can think of is that in the process of the changeover, the wires between the newly installed rotor and the spark plugs were not reconnected to the proper "towers."As a result, the spark plugs are not firing in the proper order thus causing the rough running. Since the engine will run, I also suspect that possibly only one or two plug wires are improperly connected.

Was the truck running OK before the plugs were changed?If ok before the plugs were changed then I would recheck the plug gap & check the plug wires.

If truck was running rough before plugs were changed I would look at timing & vaccuum. Also cap & rotor. The converter can be a problem with rough engine perform. Check for bad gas.
