P219a Code

[bam_da_11]

I just bought a 2011 Camaro SS 7 days ago. Like most I wanted it to be louder so I took it to a local muffler shop and had the stock mufflers deleted but kept the resonators. This was about 4 days ago. Then yesterday I get a check engine light on. I took it to O'Reilly auto parts this morning and had it scanned. It came back with the code P219a air fuel ratio imbalance bank 1. The sales person said I had the code twice so probably bank 2 has the same issue.

Would this be caused by the muffler delete? Is it something I need to worry about? Would putting mufflers on the car get rid of the code?

Thanks for the help.

Ever get this fixed?

I'll just sit over here and wait for your reply.

I have taken to just unhooking the front ECM connector and hooking it back real quick when it does it to me to get the AC back on. Sometimes it'll go a week and sometimes a day. Dealer doesn't have a clue.

My sensor measures good. My continuance to the ECM reads good and I've changed the thermostat out.

Hell the old sensor read good too but I changed it anyway just in case.

This is a pain in the ass.

Proper tuning corrects this.

I'd like to just find out why it started doing it. Surely the computer didn't change all of a sudden. Has to be something physical no?
