    Question about DTC's

    I have a 2006 Trail Blazer that I have a few codes on. By Googling the code's I assume I need to clean the throttle body but I still don't understand the fuel trims being messed up and no O2 readings. Any suggestions would be very appreciated. Thank you.

    Anything you want to log you have to put in "Table Display", doesnt seem like you put everything there.

    Next fuel trims lean is due to the LTFT at +~11% I would think.

    TB could be going bad that is why you are getting a performace issue.

    Seems you have an I6 in that? Your LTFT bank 2 show 100%, take those off of the table display and any part of the log.

    Read the how-to's on setting everything up.
