Sounds like you have a combination of problems, first clean the throttle valve and ICS passages, if that doesn’t help then you could have TPS and ISC grounding issues. As usual you should get the codes and go from there.

Sounds like the throttle return spring is missing or damaged. Hope that helps! Jim
