2002 grand caravan idles a bit low

I have a 2002 3.3L grand caravan. It used to idle smoothly at about 700rpm. Now thw idle has dropped to about 600 rpm and idles a bit rough. What could be the cause? Could it be the TPS? Thanks

Welcome to DF
Have you try cleaning the throttle body and AIS motor first. Then replace the TPS, But only use a mopar sensor if you do replace it.

Thanks! I cleaned the throttle body and it seemed to have helped.
How do I clean the AIS mototr? Is it easy to remove?

If the Idle is fine, then leave the AIS motor along. It has only one 25 torq holding it to the throttle body.
