Having performance problems with my car. It started with codes of 1-2-1 and 2-1-2. I have replaced both the oxygen sensor and mass air flow sensor. That got rid of the 1-2-1 and2-1-2 but gave me the 3-2-2. Not really sure what to do or where to look next. Any advice would be helpful and very much appreciated. Thank you for your time and knowledge. DAZED and CONFUSED !
