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. John |

Caravan rough idle
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. "John61" > wrote in message ... > Hi, > > My 94 Caravan 3.3 (180K Miles) recently started rough idle in all gears. > But seems ok when the car is moving.

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. |
