Asked by Sep 01, 2016 at 10:56 PM about the 2008 GMC Sierra 1500 SLE1 Ext. Cab 4WD

Question type: Maintenance & Repair

I have a 2008 gmc sierra 1500 that loses
rpm's, stalls at stops and when I try to
make a turn, its also jerking hard into 2nd
gear, I already took it to a mechanic and he
told me that the catalytic converters were
bad so he changed both of them out and
also replaced the cam sensor and crank
sensor then restarted the ecm and it did
nothing, truck is still running horrible,
PLEASE HELP

Do any of the warning lights come on. I would check the oxygen sensors.
