    Intermittent shut down issue

    Unfortunately there is no consistency in when, where, how, or what the circumstances are when it happens. Hot, cold, idle, highway speeds, it is completely random. This weekend in fact, not that I have stopped driving it completely, I stared it up to keep the battery charged and the fluids...

    Hello all! So my 2003 Yukon XL is having a temper tantrum. For a while now I have been having random engine shut downs. No check engine light, and actually no lights at all except the battery light. I was thinking it was a fuel issue, however that seems to not be the case. I was wondering if...

    Reduced engine power....anyone have a stick of dynamite??

    Been getting the same codes from the jump P2135 P1515 P0120. The throttle body I changed due to a roughness to the operation by hand I read online of those having and issue with that.
