P0172 & P0175 2015 Suburban Ltz
2015 Chevy Suburban LTZ 5.3 with 110,000 miles. At idle ONLY, I keep getting P0172 and P0175 codes. Not always, not everyday, but if I'm idling for a while the check engine light will come on and it's always those codes. DOD/AFM has been removed by a mechanic, the whole engine has been redone...- FarkM
