I have a 1995 Chevy Cavalier 2-door coupe with the standard 2.2 liter engine. It has around 140,000 miles on it but it's been well maintained, regular oil changes, tune-ups, gas treatments, etc. Recently, every time I push that car up to 70 mph, It will lurch and then begin to decelerate slowly. No pumping of the pedal will reset it but it usually lurches a second time and the acceleration comes back on line by itself. The check engine light sometimes lights up when this happens, sometimes it doesn't. I've had it plugged into a diagnostic computer and it shows that I have a bad EGR valve and an air conditioner compressor problem. Also, the head gasket is showing signs of leaking. I'm considering repairing it, but no mechanic I've been to can tell me if fixing the EGR valve, AC, or head gasket will help. The labor for the head gasket is a little cost prohibitive given the age of the car. Has anyone had this type of trouble with a Cavalier and is it worth fixing?

Replace the EGR, it is the culprit.

I believe you have a leak somewhere so your coolant recovery system isn't working properly and you just think you have enough coolant. Fill it up at the radiator opening, leave the cap off and watch the coolant. When the car warms and the thermostat opens, you should then see the coolant flowing past the opening. Put the cap back on and then check it every morning for a week, If the level goes down, it's time to start looking for the leak. Replacing thermostats isn't going to change anything and leaving the thermostat out of the car not only makes it take longer to heat up, but it will have the car running in a less than optimum setting and cause later problems with your O2 sensor and catalytic converter. The leak is probably the reason you overheated the first time and were running hot, because the system wasn't building up the correct pressure to keep the temperature lower. You can also check your fan and see if it turns on but I think that's working fine. Good luck.

My wife's Cavalier had a bad computer. It now has other problems. It acted much like you described. Due to other issues, I had the engine replaced. The replacement engine behaved the same way. You might consider a second opinion. If the EGR valve isn't too expensive, try it first. It might be time for another vehicle. Get another opinion before making a decision.
