Hey Guys- I had my SES light come on and took it to AutoZone to have the code read- P2A03. Fuel ratio AF sensor 1 bank 2 circuit range performance fault. Possibilities are
1.Intake air leak
2.High fuel pressure or leaking injector
3.AF Ratio sensor heater circuit fault
4.Failed AF sensor
I did a search on this code on this site and only got info about a CAT flange exhaust leak- I did recently have the Driver Side Cat Convertor replaced - could that be the culprit? Any help or advise on this would be greatly appreciated. I don't make a lot of money so I am looking for a cheap (inexpensive solution) any ideas? Help!!

Thanks N.Y.X. I will take it to the shop where the work was done- i am sure it is still under warranty- hope that's it and I don't have to eliminate issues one by one!!
