Question about 2000 GMC New Sierra 1500
I have a 99 gmc sierra with 5.3 it takes about 7 seconds starter turning for engine to start. When it idles it runs very rough like miss fire
and exhaust smells like unburnt fuel or possible rich mixture? I also
noticed fuel runs out vacumn line when unhooked from fuel pressure regulator. Fuel pressure is running 50 PSI.
Needs a valve adjustment. I assume its EFI, eliminating the possibility of the carb.
