Rough idle after plug/wire/rotor/cap change
We changed all the above and now it idles rough after it warms up. Above idle it runs great. Starts right up and during the warm up cycle it runs good but after it warms up, at normal idle of 650 rpm, it misses every so often. Sometimes worse than others. Don't know.

Rough idle after plug/wire/rotor/cap change
Was it rough before the change?
if not:
are the plugs seated and correct as to each plug from the distr?
if ok...have a multimeter to check each plug wire to be sure they are not open?
if it was rough before your tune-up..check the TPS (throttle position sensor on the outside of the throttle body..it can be checked with the multimeter for voltages and resistances at idle and at open throttle with engine off.
ask here again for ref voltages if you need them
