I would still like to read the codes so if anyone has information on how to do it on a 95.5 it would help. But for now maybe someone can help troubleshoot. From what i've read the most common problems for this are: o2 sensor, egr valve, and a long shot of battery?. I read the stuff i could find on the egr valve and how to clean it, but i couldn't find it on my engine. Also I got under the truck and looked for o2 sensors, it looks like mine only has one sensor which is before the cat. The only reason i put the battery in here is cause it looks quite old and the connections are corroded, but it still cranks fine, so i'm not sure if that is a possibility. Anyway, my trip is supposed to continue in McCall about 120 miles away, so i would really like to get this figured out this morning so i can get up there.
Thanks!
