Reduced Engine Power and CEL
Today while driving, I got I got a Reduced Engine Power warning along with Stabilitrack and a bunch of other codes. I pulled over, restarted the engine and was left with just a CEL. It drove fine to Autozone where they diagnosed it as P2138, having to do with throttle position. When I left Autozone the CEL was gone. I'm assuming this has to do with my Vitesse Throttle Controller, although it has been fine since I installed it around 6 months ago. Is it actually harming my car? May just be another excuse to get a tune along with my range device causing Stabilitrack issues on start.

It has happentd to me before. Like you did, stopped, restarted and it went away. I don't let it bother me since I love the controller.

Probably the VTC, however the Throttle position sensor does go out (went out on my 2010) and I had to replace the pedal assembly (70 bucks).

That CEL comes and goes on my car like once a week per month. It is annoying lol. Its the throttle body, I have a 95mm BBK, ported.
