Weird AFR and fuel trims P1170 P0171
Recently been having an issue with my fuel trims. They will usually be okay cruising but under load or on off throttle they will climb gradually up to the point I threw a P1170 P0171 with a gas smell in car. Also noticed when on off throttle while driving my AFR well briefly jump around from 13-15. It's almost like it's always hunting for the right ratio. Please help this is driving me nuts.
