PO172 (System Too Rich, Bank 1)
Can anyone tell me more in depth what this code means, and more importantly, how to fix it? The guy at AutoZone only told me the O2 sensor, but wouldn't really give me any more information than that. They also wanted like $350 for it!! Is this normal? I need suggestions, please!
