I was doing some testing yesterday and after a WOT pull the car started acting "funny". It was running rough and fuel trims went from -2% to -20 to -30%. I was convinced it is was a broken rocker/spring/spark problem. I haven't started turning wrenches yet.
This AM I was reviewing the log and see that shortly after the pull the MAF went into a failed state. I have never seen this before randomly in the middle of driving.
I tried to open the tune file and got this messageThen I noticed the file size was over 6 mb when they are normally 1.5 mb
I wonder if the failure was related to a real issue with the MAF or a corrupt tune? I see the spikes in the reported Hz from the MAF before the fail.
I was going post the log file...but now...it is gone!
Anyway...gonna read codes, reboot, and flash a new tune.
Edit: found the log file
