Is your 2002 Cavalier, Sunfire, or Alero giving you headaches with erratic behavior, a persistent check engine light, or refusing to start?

- Engine stalling or shutting off while driving
- Rough or erratic idling
- Difficulty starting the engine, or a complete no-start condition
- Poor fuel economy
- Harsh or incorrect automatic transmission shifting
