O2 Sensor fairly new, though that doesn't mean it can't have gone bad. I haven't yet checked it, of course.

OBD is early on the list, and will have son who lives near where the car now "living" (1000mi from home) check OBD, clean IAC again and power it w/ OBD function check utility program, clean the throttle body, check for a bad (leaking) fuel pressure diaphragm, check the ECT sensor, and test the TPS setting at idle.

Some have suggested that Radio Suppression and FP Relays can act funky when hot as well.

Hopefully, one of those will be the culpret, and I'll post when it (and I) are happy again.
