12'SROCK Posted May 7, 2007 Report Share Posted May 7, 2007 That is just like mine. My 2004 GMC VHO has 30K on here now, and I just had the BG Induction service performed on my fuel system too!!! Are we sure that the "drive by wire" trucks have an IAC valve? I didn't see 1 in the cataloging- that is, unless it is serviced only in the throttle body assm. i think the trottle by wire trucks dont have an IAC (idle air control valve), the throttle by wire eliminated a few sensors here and there.

PladdPezzPunk Posted May 7, 2007 Report Share Posted May 7, 2007 ethanol usually is the main killer, not the octane in the gas. sediment doesn't help either. Quote Link to comment Share on other sites More sharing options...
