Hi i am having an app problem i believe. the engine is a 5.3l (2011) swapped into a 1987 el camino. All parts are from the same vehicle (pedals, tps, sensors, etc.) There is a known problem with the maf and p0172 and p0171 codes. I checked for vacuum leaks and found none. Im going to try and post a log and my tune in ordinance with asking questions on this forum. Any advice/help would be greatly appreciated. p.s. let me know if i loaded the necessary parts (log and tune) wrong!
