Ok...I need help. I have a 2006 Chevy Cobalt SS/SC Stage 2 with a K&N Typhoon with stock exhaust.

During a bad rain storm, I ran thru some deep water on the street and my car immediately started running like crap. Had a hard time just keeping the thing running. Took it to a dealership (its still under warranty) and they told me it was the O2 Sensor bank 1...Well I've been wanting to upgrade the exhaust anyway. So I replaced the CAT with a MagnaFlow double heavy metal, put in Bosch O2 Sensors, and a Borla Exhaust. Doing all that fixed my stalling problem...in fact I got another 2-3 lbs of boost on the supercharger and the car runs great. No hesitation...no issues except for the engine light comes on with O2 Sensor banks 1 and 2.

The engine light on just annoys the hell out of me. Anyone have any ideas??

I would use oem AC DELCO sensors not Bosch. I had issues with the Bosch sensor when my O2 went out, than I switched to AC DELCO and problem was gone.

Can anyone give me a link to the ac delco oxygen sensor part number that I need. I'm needing to replace the one after the cat converter , getting a p0141 and p0036 code on the interceptor. I went to an auto parts store today but they want $80 plus tax for a bosch oxygen sensor. I know I can find it cheaper on the Internet or eBay.
