2014 Corvette C7 Z51 with new injectors (AUS Injection), new spark plugs (original GM), new oil, new MAF (original GM). Air filter is not attached tho
What do you think of those readings after I changed upstream O2 on both banks and the MAF?
Still having misfrires on cyl5 and rough idle and mid range. Narrowing it I can exclude O2 and cats from the equation right?
See attached full scan file for more details
