So heres the deal

I have a 2005 WRX, with currently just a catback exhaust. I uninstalled my Cobb AP because it was hiding my check engine light (o2 sensor heater failing), so now i have a check engine light. Im pretty sure it has to do with my bad 02 sensor, but on the way back on the freeway, when ever i hit even a little boost, my car would jerk a little bit, and it would only hit about 8psi. I unplugged the battery to reset the ecu, and it fixed it, I was back to 13psi. I drove another 25 miles or so and it happened again. I couldnt find another thread on this so just some confirmation that this has to do with my 02 sensor and if this is hurting my car in anyway. Thanks in advance

(not sure if this shuld be in engine managment or engine performance)

well you might want to confirm that the CEL is the o2 sensor

i did im just not sure about the low boost thing...i already ordered an o2 sensor, im just wondering if the ecu is limiting how much boost i can get up to
