My truck runs beautiful except the throttle sticks. I've got it set to run a 500 rpm at idle but when I pull up to a stop light/sign it sticks at about 1,000 rpm until I goose it then it will release and go down to 500. It is an annoyance to be sure and is slightly dangerous when I'm braking and have to get off the brake to goose it.

My question: What would you all recommend to lube the "joints" in the linkage to help with this? Also because of all of the work I did detailing the truck I don't want grease all over at least until I've had it for a few years if possible.

Thanks in advance!!!
