Throttle servo glitching

[ProStangRacing]

So as we all know the Redcat servos aren't the best in the world....mine caused my XT to go full speed into a curb. Needless to say a couple of bucks later the truck is back to new but I recently installed a HiTec 645mg throttle servo in the truck and it was glitching so bad it was going to full throttle! Any ideas on what's gong on with it? I tested it with to different controllers and receivers and it does it on both. When the engine is running it glitches violently. Thanks in advance guys

Get a NGK spark plug, the stock one will do that to the electronics.
