Gen 9 Problems/Service Issues/Troubleshooting
Alright this is a mess so I’ll keep it brief
2016 Malibu
check engine light went on - p0299, p2227
Went to drive it home - white exhaust and limp mode
Cleaned maf sensor - no more exhaust , intermittent limp mode, check engine light off
Since then, car unable to accelerate quickly, hesitates...
