Caravan rough idle

Hi,

My 94 Caravan 3.3 (180K Miles) recently started rough idle in all gears. But
seems ok when the car is moving. It shakes a lot with the rough engine
anytime even in Parking and Neutral. At red lights I often feel it's going
to stall, but release the brake, it runs fine.
Any advice is appreciated.

If plugs and wires are known good, then thoroughly clean the throttle body
and choke plate to solve your problem. A can of good fuel injector cleaner
(Dupont Techron) in the tank won't hurt either.

VAcum leak or egr valve. If egr it will not throw a mil like the newer (96
on) will.

Have the vacuum check. Look around for cracked or broken vacuum hoses.
An engine will idle rough and/or die at idle if there is a serious
vacuum leak. Do you have any trouble with the A/C vent changing
between floor/dash/defogger? That's usually controlled by vacuum. I'm
not familiar with the caravan, but thsi is common with cars.
