not sure what its called (i think dad called it linkage) its what controls the gas pedal. that seems to be sticking a bit. i have included pics and circled so you can see what I'm trying to say. when i let off gas it causes truck to idle high, and by looking that piece isn't sitting straight. i can push it to the right a bit so it sits straight and the idle lowers like it should. what do you call that piece so i can replace it or any advice on how to get that fixed where it doesn't idle high?
