Engine Performance problem
2003 Chevy Silverado V8 Four Wheel Drive Automatic 106000 miles
03 chevy silverado. Getting an intermittent rough idle and has a mass air flow code as well as a 171 and 174 codes (lean condition) replaced the spark plugs/wires, mass air flow and fuel filter. Also tested the fuel pressure and came out ok, but still getting the rough idle. Runs great at any speed besides idle. Any thoughts?
