Hi all,
2011 Silverado 5.3 with original 6 speed swapped into 86 C10.
I originally had it tuned by a "tuner" and was not satisfied. When it was tuned, I did have the original air intake with a little modification for a cone filter as the OG filter box was sold when I bought the engine. I do not remember if this code was present at that time.
Eventually I make my own intake with AirAid universal kit and a MAF housing to go with. I believe this is why I have these codes but not sure. I have checked for leaks and do not think I have any. The front vacuum is blocked, the side one is connected for the AC vacuum, and the brake booster one. I have gotten decent at tuning the transmission, but have no clue on the engine side and need some help.
I am not asking for any secrets or anything, just want to permanently clear these codes. can someone please hep me out?
final w time set to .5.hpl
