I purchased a 1996 Chevrolet Lumina. The service engine soon light came on. The dealer stated that the car had been sittin on the lot for a period of time and that is typical. I had the light checked at an AutoAone. The code was EGR flow insufficient. The EGR was replaced with a new unit and the code erased. After a day or so the Service Engine Soon light came on again and the same code. How do I stop this from happening again?

The only way to stop it is to deactivate the CEL (bad idea) or find what the problems really was. It could be a simple as a loose wire.
