Pulled code P2A00
Hoping someone can help
After a long weekend I installed headers, test pipes, MREV2 and a 1/2" spacer with my Injen CAI.
Some of the probable causes of the code seem to be:
1 - Excessive rich or lean condition (I would think lean as my MPG is fine)
2 - Exhaust leak near sensor
3 - Failed AF sensor
I heard that this will cause the engine to run lean, can anyone confirm this? I am going to a dyno tomorrow so I should find out there.
I tried to be as careful as possible with the O2 sensor. Anyone have any general troubleshooting tips I can check tonight? Thanks.

OK - it's the Bank 1 AF sensor 1 - MOST likely electrical in nature.
Check the harness and make sure nothing is cracked, pulled, etc.
It is likely reading a short - for that specific error code..there are other codes that will read for a bad sensor, stuck fuel/rich setting, etc.
Let me know what you find. Others that have had this issue - have removed the sensor and put it back in, cleaning the electrical contacts - and all was well.
