2008 Chevrolet Equinox - Still Sputtering AFTER replacing spark plugs & wires. I have read posts regarding a known issue with this engine and want to know how to get this fixed and have it last a while.
Changed plugs and wires at 70K and 103K miles (last week of December,
about a week ago). Air filter is good, throttle body is clean, MAP sensor is
clean...What else is there?
