Exclamation My 1994 Caravan with a 3.8L engine is surging/idle roll issue

170,000 miles, awd 1994 grand caravan.

Just recently it started occasionally having a strong surge or idle roll, especially when cold.

Twice now it stalled on me, both times at idle.

New fuel pump and filter. Vehicle has been regularly serviced, no leaks at fuel rails (replaced).

Any thoughts or ideas on what is causing this?

Question

Can you tell me the approximate location of the IAVC? I want to clean it - also the EGR valve. Thanks.
