**Disclaimer** I tried searching on the forum and Google. Didn't find this series of events but Found some helpful info about how to read data logs. And have had the OFT diagnostics up and everything "seemed" okay from what I could catch.

Threw code P219A today:

Okay ladies and gents here's the Low down. Been running OFT Stage 2 with Gruppe-S UEL, JDL ultra quiet highflow front pipe, and Corsa Catback for about 3 months.

Just added Perrin Inlet tube and a freshly oiled K&N air filter. 300miles later threw CEL P219A: Bank 1 Air Fuel-Ratio Imbalance.

Checked the sensor, and seals, everything looks to be good. Anyone run into this, or have some suggestions? I have a 3rd gear/4th gear pull recorded but won't be able to load it until Sunday most likely.
