technical glitch

[tdi250]

Hello,

I've recently had a technical glitch in which during the later part of a 5 min race. (1/10th buggies) when steering, the throttle would twitch. I picked the car up and whilst only touching the steering, the throttle would twitch. I swapped the speedo and the problem went away so it must be the speedo but wondered if anyone had experienced anything similar?

If so did you find out what was wrong?

Cheers
