Loss Of Power And Missing With A/c On

[Mentat]

Hey guys.
1993 5.0 GT. Car runs perfectly until I turn on the A/C. When it is on, it idles fine and takes off fine (up until about 2k rpm) and then it starts missing terribly all the way through the powerband. The car maintains a smooth idle after this with no ill effects seen elsewhere.

Any ideas?

Check your wires and plugs. The extra load of the a/c may be exposing a weak component in your ignition system

Roger that. I will inspect them in the morning and report back.
100F+ in Texas, I need my AC!

Thanks for the tip, man. I readjusted all my wires and it seems like doing that solved the problem.
