Four Winns Vista 2006 Throttle Actuator

[AussiePaul]

Have a Four Winns Vista 2006. The starboard teleflex throttle actuator is playing up. It goes into gear but once throttle is pushed forward or backward, the actuator goes full throttle and then goes back to neutral with an error 52.
It's unlikely I can find another actuator. I'm interested in owners that have had actuator problems and what solutions they came up with.
Thank you in advance!
