97 Grand Caravan Stalling - no codes set

Give a bit more info please like when the spark plugs, ignition wires, air filter, PCV were last replaced. When was the throttle body last cleaned properly? How does it idle when the engine is warm and stopped at a traffic light? Any noticeable decrease in fuel economy? Does it behave differently when the engine is hot or cold? Any other symptoms at all?

Given there are no engine diagnostic codes being set, I'd first suspect the basics. At going on 9 years and 130K miles, your maintenance history is very important before venturing a guess at where to look based on just the symptoms you described. Sounds like it needs the plugs, wires and filters (air and gas) replaced as a starting point if they have not been done recently. I'd also definitely clean the throttle body real well too. You may also want to try a good fuel injector cleaner in the tank as well while you are at it.

Throttle body and injector system service at dealer 34,523 (so they say, not convinced they really did the work, no marks or clean spots near or on throttle body at the time) PCV 66,130 Plugs and wires 100,957 Fuel filter 101,202 EGR valve and control 101,340 Leak Detector Pump 116,660 Trans filter and fluid 131,578 VSS-output 131,970 Air filter recently checked, clean Oil and filter changes done regularly

Maintenance pretty much followed according to schedule as recommended by the maintenance book that came from Dodge.

Other than the intermittent stalling as slow speed and buck at high speed, the van runs great. Idle is as smooth as it always has been. Fuel economy is good, no noticeable drop from earlier years. Hot or cold van seems to run the same.

The only other thing I can think of, the trans was getting a little noticeable while shifting. Particularly when coming to a stop. You can feel a nudge or bump as it downshift coming to a complete stop. As if at the last second it decides to shift into 1st gear.

Any recommendations on a fuel injector cleaner?

What is the AIS?

Air Intake Servo (I think this is right)... It controls the air mixture to the Throttle Body. Based on your nice listing of the service history (thanks), and assuming it idles a bit rough, I would start at the TB and do as was suggested by jdoe with disassembling and cleaning the TB and the AIS. Make sure you use a new gasket when you reassemble. In addition, if it was me, I'd toss a large bottle of Techron fuel injector cleaner into a full tank as well. If this does not help, I'd remove, inspect, and replace the spark plugs next before looking further to make sure these are not fouled and firing properly.

Good luck and let us know how you make out.

That sounds like a dirty throttle body starving for air as you close the throttle blade, You don't have to remove it, just take a can of throttle body cleaner and a tooth brush and clean the inside bore of the throttle body and the top and bottom of the blade, Of course do this with the engine off. The Bucking problem would be something else and not related to a dirty throttle body. Glenn Beasley Chrysler Tech

Sounds good to me. Now, what would cause the buck at highway speed? I believe the two are related.
