I know this is vague but my brother has a 1994 Dodge Caravan. 3.0L V-6 with an automatic transmission. The past few days it has started to run very rough and stall out at low speeds. Seems ok on the highway under full throttle. It is putting out no trouble codes or check engine light. I will entertain any guesses where to start. Thanks

I remember two things that were common, one was a vacuum leak behind the intake manifold near the booster for the master cylinder, the other was worn distributor cap.
Also those OBI systems didn't put the check engine on for too many issues, but I would gather a bet that there is a stored code, and if you have a scanner look at the "block learn" data see if it is near 128. If it is, then a lean condition is present and it can a stumble at idle and stalling.

Thanks I'll look into that. I tried the key on-off-on-off-on code retrival method and just got codes 12 and 55 which mean nothing is in there by that method. I am sure an actual scanner might dig up more.
