I have a 2001 Chevy Cavalier with 123000 miles.
The engine light and Trac off/low would come on with jerking, and the car would slow down. I had to pull over and restart the car. It would drive OK again, but act up again a week later.
I finally took it in to an auto service that specialized in electrical problems. They replaced the Throttle Position Sensor (TPS). It has been driving better than when I first purchased it 2 years ago. Hope this helps.
Would you buy another car from this manufacturer? Don't Know
