Answer Question
08 f150 p2198 now wont start stft -28 prior to stalling
Had iissues with bank 2 cylinders flooding with fuel. After fixing that the vehicle starting running really lean until it stalled out. Now it won't start and it's throwing code p2198 o2 stuck rich. I checked the purge valve canister( working as it should). Prior to stalling out stft was at -28% on both banks. Is it a bad o2 sensor? Or is there something else I can do.
