Stepper motor

Engine light is on. Code says stepper motor. Took it off and cleaned it, reinstalled, cleared code and light came back on. Periodically the idle will stay up around 1100 rpm for a few seconds. Seems to me it might need to be replaced. Any thoughts or ideas?? Is it as simple as screwing a new one in and lugging it in? Or does it have to be set/adjusted?

I am dealing with similar issues. Apparently there is one other thing to check and it is at the air intake side. There is a "bypass" hole in the throttle body assembly that will need cleaning. There is a discussion on it right now relating to stalling that discusses this.

I bought one that would work on a chevy astro van for around 30 bucks and just screwed it right in.

Ive also run seafoam through it and that helped with my idle issues. My truck had a lot of carbon build up though.
