It might be the idle stabilizer valve or the throttle itself. The ISV sits
at the rear of the motor directly behind the throttle. It's a valve to let
air past the throttle and into the manifold to adjust idle. Clean both with
carb cleaner. They tend to get gummed up.

Subject: BPV Symptom?
I am fairly new to 20v's. From what I've read on the forum I think I
have a symptom of a BPV problem, but I wanted to run it by the list to
see if it sounds right. On slow decelleration, like 40mph down to
20mph, there seems to some surging/seeking. That is when I let up on
the gas, it may be a while before the engine starts to slow the car. And
when trying to maintain the new slow speed I will slowly go higher in
speed, then suddenly a noticible jerk as the engine finally gets to slow
This happens at slow speeds, so it is not really dangerous, and the
engine shows no signs of quiting on decell. All the same, this seems
like it might be a BPV problem. Does that sound right? Something else?
