Engine down light came on
My 2008 GMC envoy is pulling 4 codes the first
one is a camshaft sensor the second one is a O2
sensor third one is an EVAP high purge flow the
fourth one is a throttle position sensor what could
cause the car to spit and sputter cut it off let it sit
for a few minutes restarts fine and if I'm at Slater it
does it again
