Yesterday my cel came on I went to autozone to have it checked and it came up p0401 egr flow inatiqueit( sorry for the spelling). He said that I have carbon build up in the egr valve. What do you guys think and what can I do to fix it. Please help[???]
Well i'm no expert at trouble codes, but i don't think the egr trouble code for flow inequity would be limited to just carbon build-up. It could be a leaking or collapsing vaccume line or maybe even a bad solenoid. Once again, i could be completely wrong, but i definetly wouldn't rule those out either.
Sorry i'm not much help on the matter, but i'm sure someone on here will have a good idea of what to do.
that is quite possable. I havde the egr off know and cleaning it up. I am also looking around to find any thing else. This is the first week end I have driven the car in almost 10 weeks. I have been out town for work.
