trouble code help Alright so I just swapped a LT4 motor with cc503 cam and full bolt ons into my z28. I finally got the car to start but now that its running its giving me a few codes using the freescan program that Im not to sure how to approach them. The car is also idling super rough.
Code 48 - Mass Air Flow system failure
Code 44 - Left 02 sensor lean
code 46 - Fuel enable failure
For the MAF pigtail on terminal A i was getting 5v, terminal B & C was 11.97v and terminal C was 11.98v. Does that mean that the MAF sensor is bad and needs to be replaced? And what about the other codes?
