This reply wont be of much help.....but my new to me 01 box base with high mileage surges at idle when AC is on........and does not when AC is off. I will be interested in what is causing your issue.

When time permits, I'll clean the TB and will try to report back the results here.

If the TB on your vehicle hasn't been done in while, it probably would be a good idea to clean it. On my jeeps, cleaning the TB every 30k-40K miles was a well known std practice to guard against bad engine performance.

Am actually surprised that no one has provided any comments to the original post.

Well I have to replace my starter soon....so while I have the TB off it will get a good cleaning. Good luck with your scenario.....hope ya get it fixed.
