I shut the car, turned it back on. Check engine light was still on, but driving felt normal (as far as I can tell). The reduced power was VERY noticeable.
So then, on my way toward a highway, I am able to stop/start again to try and clear the CEL, but it was still there.
On the highway, not under any abrupt or heavy throttle, I get the reduced power, as well as the Service Stabilitrack alert (along with all the dash lights). The first alert today, I was just starting off, probably still in 1st or 2nd. This was highway speeds.
I pull over, turn off/wait/turn on, and the CEL is still on but the other issues are gone. Power is back to normal.
I finish my ride to work, with the CEL on (not flashing) and power feeling normal.
Does this sound like the VTC related issue to you guys? I was going to uninstall mine and see how things go, but I love using it. Those who had this issue, did you have to disconnect the VTC to clear the CEL, or will it just clear with time (as I've had with other CELs in other cars).
Any tips would be greatly appreciated.
