[DuramaxWagon]

For two weeks my check engine light would turn on when I went up any grades, and then turn off a few minutes later. Now the check engine light has been on for the past week. Friday, I pulled a DTC P1093. After some research I thought it might be my fuel filter w/ 8000 miles on it; so I replaced it yesterday and cleared the code. The first hill I came to turned on the check enigine light again. Furthermore, my truck idles rougher after the filter change. Does any body have any experience with this code or ideas about what the problem is before I get raped by the dealer? Thanks.

Maybe it would be good to metion that I have a 02 Duramax w/ Allison Trans. - K&N Filter - Bully Dog Power Pup Downloader
