The CE light is not on. But thanks on the tip on Toolpants postings. More hunting took me to the Renntech site and then a posting pca.org that said the following

Appreciate the help - at least when I take it to the mechanic I can lead them in the right direction.

"Usually the problem would be with a sluggish Idle stabilizer or also called an IACV. These valves can get corrosion in them and slow down until they get stuck and then cease to work. This valve controls the amount of controlled bypass air required to keep the car idling. These conditions change with load and the valve opens or closes to accommodate this. The valve is easy to access from its location on the side of the throttle valve housing. This condition will usually be exacerbated with the A.C. on."
