The Car: '83 245

Symptoms: Occasionally the car will 'stumble' while driving, and the idle is a bit rough. The stumble does not seem to be related to the car being hot or cold, as it has happened both ways. A few times the car actually died, but has restarted ok. Last night my wife drove the car about 20 miles to have lunch, and when she came out it would not start. It cranked fine, but would not fire. She tried to start it several times over a 45 min period, but finally had to leave the car. I went to retrieve the car last night, and it started right up. It had one little stumble-die episode while I was driving home, but then ran fine.

Recent Work: I have recently (within the past few months) replaced the flame trap and cleaned the breather box, cleaned the throttle body and adjusted the TPS, cleaned the IAC, replaced the plugs/cap/rotor. The car has been doing this for about a year, although very infrequently until lately.

What do you think guys? AMM? FPR? I was actually excited when my wife said the car was broken - I was hoping it would not start, so I could finally find the bad part!

Thanks.
