Mileage is about to hit 100k. However these are mostly highway miles.
Running a process rev 3 tune with about 16psi boost. Don't track the car at all so aggressive driving is really minimal and usually on ramps, back roads and not back to back to back.
In regards to coolant, I recently changed my coolant myself but cant remember anything I could have messed up in the process. I will check coolant levels when I get home.
With my recent misfires I have pretty much decided my injectors are bad. Not ruling out a bad O2 since I occasionally get 4,5 & 6.
Is it possible my bad injectors could be causing this?
