Your throttle body probably needs cleaning. If this is something you want to do there are plenty of videos on You tube ---

> [@Jos29](#): > > Idling to high (1500 rpm) and fluctuaitng up & down Welcome to the forum… Do you have a check engine light on?? what are the codes?? Is this a 2.4L or 3.3L??? Sound like you have an IAC (idle air control) valve going bad, try tapping it with the handle end of a screw driver to see if it helps any… Check for vacuum leaks also… 3.3L IAC shown below… ![](https://global.discourse-cdn.com/cartalk/original/3X/5/6/5658b0f6009e7f2544e609e4929e6750a8c7f506.jpeg) ---

Good to see.you back @weekend-warrior Did you come through Milton OK? Dry? I imagine power was out for a while since your area was closer to landfall than we were. ---

Sorry for the late response. glad to see things were ok with you. We did great with the hurricane. never lost power it just flickered on and off a couple of times. we lost cable and the internet for about a day. I feel very lucky. so many lost so much.
