2005 GMC Sierra

Asked by GuruBV85B Dec 21, 2018 at 12:39 PM about the 2005 GMC Sierra 1500 SLE 4WD Extended Cab LB

Question type: Maintenance & Repair

I have changed shift solenoids, mass air flow
, throttle position sensor , all coil packs wires
and plugs , still seems to only run on one
bank , the left bank of coils has fire going
through them but when I pull the plug wires it
makes no difference , when I pull any off the
right bank it makes it rough idle ..I had a
P706 code and a random misfire . On level it
will get going but will not climb a hill
