#227 of 306 Car dies at idle, hesitates when asked to accelerate

Have a '98 Sunfire Convertible with about 140,000 miles. This car has run great for the last 100,000 miles, with the only problems being door electric window actuator and switches, and similar problems.
For the last year or so, the car has occasionally hesitated to accelerated, or tried to die at idle, especially after being started warm. Used to be able to cure this, it seemed, by putting in neutral and revving up the engine a bit.
Lately, this has suddenly become a daily occurrence, and it now occasionally shows the check engine light. Every thing else seem normal. Took it to a shop and it showed only a "rich" code.
Okay, experts. Anyone got any ideas?

Took it to a new shop in town, with high recommendations. The young mechanic had won a national troubleshooting competition. He had the car back out in the parking lot in less than 10 minutes, having replaced a cracked vacuum hose.
Turns out his dad had won the Plymouth national troubleshooting competition in 1974 also. Guess trouble shooting runs in the family.

#235 of 306 98 Sunfire Malfunctions

After reading every one else's problems, I can relate.
My 98 Sunfire was running perfectly fine. On Christmas Eve, pulled up to a red light on the Boulevard and it stalled. After 15 mins of investigation, hit the ignition switch and it magically started. Went to Advance Auto, they put a computer on it to read my computer and it said that the CrankShaft A Sensor was bad. Bought one just in case for later replacement. Had no problems the rest of the night, finished my Christmas shopping and all was well.
3 days later began to "sputter, rear and jerk" while I was driving it. Got it to the garage and replaced the CrankShaft A Sensor.. Worked fine didn't seem to have a problem whatsoever.
Yesterday, it made it 6 miles and just shut off. Started again, made it another 3 miles and that is exactly where it sat. The garage put the computer on it again, and it said that it was the crankshaft sensor. In the meantime, after cranking on it to attempt to get it started the starter went out.
The starter was put on, the cam sensor replaced drove it home... didn't make it but 4 miles and it shut off again... Same problem! To cover all bases, replaced the Coil pack module this time.
So with this being said, the Crankshaft Sensor, the Cam Sensor, the Starter, and the Coil Pack Module have been replaced.
It seems when the temperature begins to go up to normal running temp, it starts this. When it's cold it works fine.
So, what now? Any suggestions, besides junking it???
