Question about 1991 Toyota Pickup
Had a mechanic work on changing blown head gasket. now when i drive it feels like throttle sticks until you press on gas and release quickly to bring it to a fast idle. sometimes it revs up and down when warm?

SOURCE: idling high
are you using aircon? if yes observe if it beahaves OK if the aircon is OFF. Then if you turn the aircon ON does it go up? if so, you may have no freon on the system because the engine does not have a load and the aircon system is idle upping your engine.

check to see if there is any carbon on the throttle body where the butterfly contacts it. also clean the " business end" of the idle air valve to make sure it's not being held open slightly.

The grinding sound may be a throw out bearing or the pilot bearing. The sticking throttle problem sounds like a linkage or cable binding up from possibly damage due to the impact from the accident.
