HELP! 07 M8 flashed 1-8 (servo problem) I replaced servo BUT...

I need a little help here. I was following my wife's M8 last weekend through some tight trees and could smell a really strong electrical burn smell. I stopped her and had her shut the sled off. When I restarted it and drove about 20 yards the check engine light flashed once and then 8 times. The sticker under the hood said it was a servo motor problem. When I got it back out to the trail I opened it up and the sled would run right up to 20mph no problem and then fall on its face - I limped it back to town and anytime I tried to get over 20mph it would just miss and spit and sputter like it was in a "limp mode". I replaced the servo with a spare I had but the motor seems like it is still in limp mode. I can move the APV cables by hand and they return o.k. from the servo motor loacation and don't seem to be stuck.

Here's the question: Do I need to reset the limp mode? Or is there a chance that the servo motor I replaced the old one with could be the problem (it is a used unit I bought as a spare for my M7 a few years ago and I've never run it).

Thanks in advance for any help - I really appreciate it.

Get your stator looked at. just got mine replaced on an 07 m8. all signs pointed to PV issues, replaced cables and still didn't work. my stator was junk, i guess the 07's had issues with these.

Make sure that the cables don't have any resistance to them. I had a similar problem a year ago. I could pull the cables by hand but they had melted just enough that the resistance was to much for the Servo. As far as why it melted the first servo. I would look into the stator maybe? As suggested above. With the cables disconneted does the servo motor turn when you rev it with the belt off.
