I recently bought some used receivers for my FS-GT2 and both are causing this odd glitching issue with my car. When I turn the steering wheel it makes the motor stutter and stumble. I've tried to rebind to both rx's multiple times and recalibrate the MMP in my rustler. Any tips or suggestions?

Here's a video of what it does.

+ YouTube Video

Whenever I switch back to the original receiver that was in my car it stops doing this.

ESC is a MMP and servo is a Savox 1258TG if that matters.

I've had absolutely no issues running this setup for the past 3 months.

Any thoughts on what it could be?

Edit:

Another interesting thing is when i turn to the right the throttle input gets really really jumpy and needs lots of input before it does anything.

Edit 2.0:

When the servo is unplugged and I twist the steering wheel it does not start having seizures like in the video.
