when i pick the truck up from getting the bedliner done there was a CEL, the guy also said that i had a big fuel leak, I knew exactly what he was talking about , i thought that i had fixed the problem when i changed the Evap box earlier in the fall, apparently not. This has led me get Tech Stream setup so i could diagnose what is happening, i have no idea what i am looking at though when I am looking at the data... Maybe someone can translate the data on this PDF. i can tell that i have multiple misfires which points to coil packs but i washoping that tech stream might be able to provide more information.
