I need help again, I have read and researched and nothing is working so far. I have replaced the IACV 2 times already, checked for leaks and also cleaned the TB. I have done a SAS reset with the BISS Screw using Evoscan. But after roughly 25-30 miles if I am lucky the code plagues me again P0505. I have made my tuner scratch is head with consistent tries to eliminate it. Is their a way to eliminate this code on the ROM?

Trouble shooting done.
