Last Sunday on my way home, engine light came on. Car drove fine, parked it in the garage, got my device and read the code, P219B found out it was bank 2 air fuel imbalance. I cleared the error and continued to drive the car all week, error did not return, anyone else ever have this issue?

Did you ever get the code before you installed the cold air intake? If not, it probably has something to do with your cold air intake.

Yes. You should always list mods to the vehicle when asking about DTC's.

Anyway, either air leak at a connection to the intake or the intake itself causing inaccurate MAF data. Less likely-- EVAP leak. But no other EVAP codes.
