    Looking to buy 2013 yukon denali

    Update..... the 12 model that my boss has, no idea of who or how long ago the swap was done or how it may have been driven since. As for the 13 model. I went to test drive it Saturday and as I parked my truck the salesman backed it out of its spot and I didn't even drive it because it was...

    Looking to buy 2013 yukon denali

    Hello, I'm looking at a 2013 yukon with the 6.2 engine. I have recently test drove a 2012 yukon denali, for several weeks, that belongs to my boss. He owns a used car sales. The 12 model has the afm deleted with long tube headers, head studs, and what seems like aftermarket cam. It runs good...

    Reduced engine power without cel

    I've looked at it and watched it on live data and the % don't match perfectly but they do change in relation to one another together. Any idea how much they can differ and still be normal?

    Reduced engine power without cel

    What should the numbers be? Do this at idle or try to see what they are when it goes into reduced power? I normally work on all my vehicles and I know what long and short fuel trim is, but I don't really know much about using scan tool other than the typical check codes stuff
