the TCC solenoid has been a problem on GM vehicles for years. i had a 94 cavalier with the same problem. you should be able to unhook the wire and see if that fixes it. if it does, that was the problem.

that still sounds like the TCC solenoid. mine would stay in gear and jerk violently when i slowed down and when i tried to start it. once i unhooked the wire to the valve, i never had another problem.

try looking at the fuel filter then clean your injectors.It could be some other things but check them first

Car dies at idle, hesitates when asked to accelerate by tarheeltom

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.
