I believe mine keeps an EGR code. My CE light is either burned out, or the bulb was yanked by a PO. The EGR code is easy to live with if you don't know it's there.
This is EGR light since buying it new in 2002. There is something that is the EGR to foul quickly. Anything from poor spark to bad gas to a leak of some sort
