84, 3.2 Rough Idle
Rough Idle when hot, otherwise fine when driving and no trouble starting up when hot.
Starts right up and idles fine when cold. O2 sensor? Any thoughts would be appreciated....thanks...

Disconnect the O2s and see what it does.

When's the last time the ignition wires were replaced? Sounds like with increased heat, there's more resistance on the wires & spark becomes weak. May want to do a resistance test with a DMM. If they're original, buying a new set may be a good idea anyway...

Check for vacuum leaks first.
