So the intake resonance valve was the reason the car would stutter under light load and rpm fluctuate/stall completely. One issue down!

Tried replacing the shifter and OVP, but no luck. ABS light on, cruise control off, and no 5th gear.
I actually got a new fault 5 on pin 14 for the stop lamp switch AND pin 13 (Transmission) is giving me a solid light now. Just yesterday it was fine and read no codes. Got to go retrace my steps with the shifter and check.
