Wow, thanks Etlsport, we would have gone a couple more posts before I figured that one out! At 90k+, it could be anything, so the fuel pressure regulator may be bad, haven't smelled the exhaust in a while, honestly I try to hold my breath around it, as far as I remember it smells like exhaust to my simple nose, I will pay more attention next time to see if I smell anything odd
For that matter, how easy/hard would it be to replace if I wanted to just do it anyway? I'm figuring with the mileage it wouldn't hurt
