that rod should move when you jump on the gas. in park a quick short rev it should move on its own. if not, then you should change it. as well if it dont move on its own.

also make sure a vac line to it is not cracked, i redid most of my vac lines when i did my lim due to all the rubber ends breaking when i took them off.

if theres a leak to the actuator or boost solenoid it wont work.
