When the van is warm, and the brake pedal is depressed, the idle drops and it almost stalls. The van lunges forward when it wants to stall. It starts fine. accelerates good. I have replaced plugs, cap, rotor and the idle air control valve. I have also clean the throttle body plate. Basically if you were in line for a drive through bank or waiting for a long light it would happen. It takes about 7 -10 seconds with your foot on the brake pedal for the stumble to kick in. But still does not have a nice smooth idle even in park.
