Plymouth voyager stalls

I have a 1996 minivan with the 3.3L V6 with 77k. It started stalling intermittantly 2 months ago. I am able to start it again; lately it takes a couple of times, but does start.

The vehicle has these symptoms:

- can stall while at a stop, slowing to a stop, turning corners, while accelerating, going any speed, including 70mph!

- noticed today that after accelerating, took foot off the gas, tach drops below 500 rpm then sometimes bounces back to 750-1000, other times drops to zero and stalls

- Service Engine Soon has come on once then went off by itself

- fuel light was going on and gauge would go to empty, after filling tank but has not done that this week

Replaced the following:

- Plugs and wires (dealer)

- Coil pack (dealer)

- Throttle body - only cleaning (mechanic)

- Idle motor (mechanic)

- Fuel pump (mechanic)

- Fuel filter (mechanic)

$1000 later, stalled 9 times just today. Still intermittant. Mechanic wants to replaced the computer now. When mentioned turning corners, maybe gas tank baffles, but stalls on straight away.

Called Chrysler, said all cars can stall at speed. Weary about going back to dealer but they have a "copilot" device haven't tried yet, whereas the mechanic does not.

I have looked at other posts, and I have tried some recommendations. Still stalls. Any help would be greatly appreciated! Thanks!

You need a new mechanic. Throwing parts at a problem is NEVER the way to fix it. Find a good diagnostician who has a good scanner. Such a scanner will allow the tech to drive the vehicle while the scanner monitors all of the electronic communications going on under the hood. When the engine stalls, the tech can press a button that stores the previous 20 (or 45, or

60, or 90, etc.) seconds worth of data readings for analysis. This is the kind of diagnostic technique it takes to nail down an intermittent problem like this -- not just random new parts, which is what has been installed so far.

Horsepuckey.

YOUR mechanic doesn't. Every up-to-date mechanic does. Find a new mechanic.

You don't need a mechanic. Your car did not respond to a mechanical analist.

You need a lawyer.

If air planes were made like cars, a thousand would crash into the ground every day.

You *might* want to try replacing the battery. I kept seeing both the speedometer and the tachometer on my voyager lock at zero while driving. This went away with a new battery. The implication is that the computer does not operate correctly if the battery is dying. If the computer is not operating properly, all kinds of problems could occur.

I have also been told that some of the speed sensors can fail. I don't know if this could cause the symptoms you are seeing, but it might be worth investigating. Does your mechaninc have the necessary equipment to get the codes out of the engine/transmission computers?

I have recently seen the fuel light problem, but after ignoring it for a month or 2, it seems now behave normally.
