The issue is, when I am slowing down, the idle basically will raise itself to about 2k then slowly works itself out to 850 rpm, this ONLY happens when my AC is on. When I have no AC running, idle drops down to normal quickly. This only happens when I'm slowing down, otherwise starts up no problem, no missing, car runs smoothly and has plenty of power.

I've recently replaced

timing belt w/ tensioner
all vacuum lines w/ silicon lines
new air filter
new distributor rotor and cap
cleaned tb
cleaned MAF
front O2 sensor

i'm not really sure what is causing this and it's starting to drive me nuts. It's an odbII motor 160,000 on the clock. Car is stock, except for a vr6 exhaust and an unknown brand chip.
