I couldn't get the truck to stall running on 1 cylinder....still think I have a bad injector....engine has slight misfire at idle...enough to rock the cab very slightly....bubble test this weekend along with overhead and egr tuneup....gotta have a bad injector...even with using "Georgia overdrive" pulling 25k downhill cant get more than 5.9mpg ...

Waterloo's truck was like this for couple years .. nothng revealed why his fuel mileage sucked, every test and check passed that anyone could think of .. ECM went dead one day (likely for a different reason), and when he replaced it, his fuel mileage jumped from 5 to 9.

Not saying that is your problem, but makes me wonder how many people drive around with this type of issue.

You might be onto something here rawze....how can I get multiple codes one day, run the truck on insite to check codes....and the very next day no codes at all...no check engine light...lol.
