My 2004 gmc envoy xuv sputters when driving it
Get codes read by auto parts store, and most do it for little or nothing.
the code(s) will give me a better idea of what may be happening.
Spark plugs could be worn out(anything over 80k miles)
Fuel regulator, injector(s), fuel pump also could be at fault.
one more a vacuum leak.
Don't be afraid to ask questions, and there aren't any dumb questions.
Codes don't give you the part to be replaced, but give you an area to test in.
