No that one ( the gas cap) got me a long time ago. Hopefully the dealer will just replace the EGR valve and I will be on my way. Apparently it can get clogged. I checked all the vacuum lines and nothing seems to be loose or leaking. Thanks AMX we have a really nice MATCO code reader and the corresponding code book, just wondering if anyone knows or has had experience with this particular code. I see a lot of codes semi related, close to but not this one.
