2001 Chevy Silverado 5.3l misfire

Asked by Brantley_Edelen May 23, 2020 at 12:44 PM about the 2001 Chevrolet Silverado 1500 Extended Cab 4WD

Question type: Maintenance & Repair

I have a 2001 Chevy Silverado 5.3 vortec and I’m
am currently having issues with a cylinder 7 misfire.
I have tried everything from new plug, new wires,
and new o2 sensors. I’m sure there’s more I can’t
think of right now. It has a rough idle and when I
pull the plugs off 7 & 8 cylinder there’s is very little
change in in the idle. Please help me before I take
this thing to a mechanic and get screwed out of my
money.
