Code p0171 and p0420. I have replaced everything in the car that these codes state. New thermostat, catalytic converter, both 02 sensors, exhaust hose. Fixes for a few days to a week and the same codes keep coming back. Now the button on my gear shift sticks keeping the gear shift from locking into place. This stops me from being able to turn my car completely off and removing key from ignition.
