With my 2007 Isuzu I-290, 2.9 liter 4 cylinder ,57,123miles, while braking at slower speeds, with the ac on, the rpms fluctuate up and down from 1200 to 500?

Is your check engine light on? If so get the codes pulled.

One thing maintenance thing you could do that may help, would be to clean your throttle body with a small brush. Open the throttle and clean the plate & body good, then a few shots down it while running..... See if that helps..........

Check engine light does not come on, truck runs fine otherwise, makes 20 mpg with regular driving....?
