Hi,
1998 Chevy 1/2 ton 350 with 207,000+. Still running good with minimal oil usage. Mostly Hwy miles.Been getting a service engine soon light. Remembered that dealers used to read them for free, ya right...Went to an auto store and it reads as a P1404. Did a little research and a few questions later it could be a stuck egr that will respond to brake kleener or a misreading of the closed position by the computer.
Anyone have odds on which is more likely?
Thanks
