i recently did a dod delete on my 2012 caprice 6.0 liter i tried to tune myself and couldnt get it to idle
i gave it to a tuner and we are trying to figure out a problem with the car, i will attach logs to this write up
i can be driving it at 45mph in 5th and 6th gear and it has random lean spikes ,it will jerk or stutter from what i can see in the logs ,the fuel pressure is constant ,the map is reading steady ,its not jumping around ,there are no misfire codes ,the maf is failed ,it is a sd tune now.now today on my 4 mile trip to work it has gotten really bad and it had enough and went into reduced power mode ,it lean spikes at idle ,my afr shoots from 14 to 17 randomly at idle, i just want to see if anyone here has any more insight,the one log is a 15 mile trip and the other is a idle log.
