So my 06 has a hard miss with flashing check engine light the code that comes up is p0036 which is bank 1 field 2 (downstream o2 sensor). I had the head gasket done got hot once and didn't want to risk it, it's had new plugs coil n ignition module put a new o2 sensor on it n still doing the same thing. At idle you could barely tell there's a miss but hit first n take off the miss is so hard she almost won't go anywhere any ideas for what could be causing me problem
