Hello
Brand new to the forums, thanks for having me.
I have a 2016 2SS that has a P00C7 Engine code. About a week ago I had a P2227 and a P00C7. I replaced the Mass Air flow sensor and the Map sensor. Reset codes and drove the vehicle for a week with no CEL. Tonight the check engine light came on after startup. After scanning the system the P2227 code did not come back, however the only code that was present was the P00C7. The CEL never comes on while driving it only comes on after an initial startup. Has anyone ever had these codes? does anyone have any suggestions on where to look. I was thinking my next move would be to smoke test the system for vacuum leaks. Any ideas? Thanks in advance for any insight to this issue.
