working on an 05 lly for a friend, he just picked up this truck for cheap, but it doesnt run rite. it will start up and idle perfect. but u put in gear it has no power , just hesitates and smokes white/black. when it first got here i checked for codes with my old bully dog, and it had 3 codes i wrote them down but ive since lost the paper
. i know 1 was p0202, 1 was either p0192 or 193. and the other was p2149 im pretty sure. so i cleared the codes, and i did the gm injector connector fix on 2 and 7. same problem. so i talked to a couple people and we all kinda figured it sounded like the fpr, so that was tonights job. well it didnt fix it. it doesnt hesitate quite as bad, but it still does. its never thrown any codes since i cleared them. when i rev it up in park it starts to hesitate around 1800rpm to around 2600rpm then seems to be smooth over that, but smokes bad the whole time. I know i need to get someone with EFI live or a tech2 to look it. but wut do u guys think?? 1 or more injectors possibly bad?
thanks
