Bad Idle

My 1992 Ford F150 with 302 engine.When put in park the engine will surge up and down 3 to 4 times before resting at normel idle.also when the relay for air or heater kicks on it will surge more than normal. Any advice? Thanks for your time!

The idle issue is probably a combination of dirt in the throttle body and a bad idle air control valve.

Clean the throttle body with Ford approved cleaner and replace the idle air control valve.

That should do it.
