We had a huge snow storm here in MA. I was driving the car last night in some very deep snow. This morning I noticed a Check Engine Light. I went to Autozone and they told me i have the following codes: P0150, P0151 & P3027. Seems like the first two trgiggered the check engine light caused by a malfunctioning O2 sensor.

First question I had was does anyone know of a 4.8i DIY for this, and secondly is it possible I hit the sensors with the snow and it came loose?
