P2A03 A/F Sensor1 Bank 2
I've got this code for one of the up-stream A/F or o2 sensors (not sure if there is a difference).
Previous owner installed Fast Intentions long tube headers and I'm not sure where that leading o2 senor would be.... the cats get eliminated and it looks like the upstream sensors are too.
I managed to grab screen shot of the voltage readings of all 4 sensors at idle and the short term and long term trims for both banks (both attached below).
2 concerning things-
-bank2 sensor2 varies hardly at all compared to bank1 sensor 2.
-short term fuel trim for for bank 2 was 21.1% compared with 4.7% for bank 1.
Thanks for looking and I appreciate any help with this.
