    Fiesta Rally Servo Drifting

    I have a new to me Brian Deegan Ford Fiesta Rally with a castle motor and speed control. I have been working on going thru the front and rear diff replacing the oil. I got it back together and noticed that the steering servo drifts on its own to a full right turn and then snaps back. It seems to do it more while accelerating than just sitting still. Has anyone run into this and would it be the steering servo or possibly the speed controller? I didn't notice this the first couple of times I ran it. Any thoughts would be appreciated.

    Thanks

    After some investigating, I found the problem. Not sure why I didn't think of it sooner. I will blame it on it being late last night when I got it back together. So with the TSM at about 50% it is enough to make the steering act erratically when suspended on the lift. It isn't noticeable when actually driving the car because it is going straight and doesn't need correction. Simple fix, turn off the TSM and the steering doesn't jump around on its own.
