Re: Rough idle with misses and vibrations

["Wm. Josiah Erikson" <werikson@hampshire.edu>]

I would:
1. replace spark plugs, cap, rotor, wires
2. replace injector seals... while doing this, check injector spray
patterns. If one is really bad, then replace it.

You could also check for vacuum leaks. Make sure your ignition timing is
adjusted properly.

    Good luck!
