With a little over a gallon through my MT, my throttle servo decided to die out on me. Frustrated! Luckily I was just driving around slowly and wasnt gettin too carried away! The servo will extend to throttle, and wont retract. If I move it back by hand and pull the throttle it works but still does not retract. I tried it on the streering channel as well. So I know its the servo. So, what is a good solid cheap replacement?
