new truck.. new problem

[swarmjt]

throttle servo is sticking bad.. any ideas? ill give it some gas and let off and it keeps in the gas? it eventually goes to idle but it shouldnt do that.. it is a brand new out of the box CEN matrix.. steering is good and very responsive but throttle keeps going?

Is the linkage set properly? Meaning, does it pull straight and smooth? It's kinda hard to diagnose and linkage issue via text. If you work the throttle (engine not running) and pull full open, hold it and then release to neutral does the linkage hang up, does the slide return to closed? Does it return and if you push on it go a little more? Are you using a rubber band or throttle return spring? Outside of mechanical issues, what are the temps you're running in? Cold and high humidity can play havoc with engine tune and LSN settings.

pull throttle wide open.. it slowly returns to neutral. i can hit brakes and it goes right to it??

Try making the throttle return spring so that it is stiffer and has more push.

There should be a couple stopper things on the throttle linkage with grub screws in them. Unscrew the one that contacts the throttle return spring and make the spring tighter (if it stretches when throttle is open, stretch the spring out; if it compresses when you apply brakes, compress the spring) then tighten the screw.
