1997 Chrysler Plymouth Grand Voyager 3.3 Liter V6 Engine intermittent stalls out

15

Asked by Mar 30, 2017 at 05:05 PM about the 1997 Plymouth Grand Voyager 3 Dr SE Passenger Van Extended

Question type: Maintenance & Repair

What do you think is the cause of this?  My mechanic can't pin point it. I'm
the original owner. Well maintained.  Approx 190,000 miles. Throttle body
cleaned. MAP Sensor replaced. Mechanic carefully inspected all wiring in the
engine compartment, near the trans and wiring harness, etc.  All dashboard
displays function properly, so no obvious electrical disturbance is afoot. This
issue happens very randomly, without regard to temperature, weather,
speed, etc.  It has stalled at a light and while doing 40 MPH. Sometimes I'd
experience a slight shudder before the engine shuts off, or other times not. It
will just shut down.  When this occurs, all problem lights on the panel come
on and power steering shuts off.  Here's the one thing that was done to the
van just before this problem appeared:  I had the transmission rebuilt.  A few
days after taking home the van after the transmission rebuild was done, this
random engine shut down problem started to happen.  Otherwise, when it's
being driven, it runs smooth as silk.  Any ideas???

Also, I did purchase one of those engine code readers, and the MAP sensor error code comes up whenever this thing shuts down. My mechanic explained that the sensor is responding to the internal goings on of the engine by producing that code, because of some electrical problem which is likely the root cause. He thinks that this can one of many, many things.. probably something like a short electrical connection somewhere in the system.

Also, I'm currently giving the fuel system a nice cleaning by adding extra fuel cleaners like Gum Out All In One. My research indicated that clogged fuel systems or clogged fuel pumps might cause this situation. OK, I'll admit it... I'm trying to milk this baby until the bitter end.

Update! I have been feeding this van Rislone gas treatment for several weeks and the problem has been happening less and less. Thinking it's a fuel related issue, I had the fuel filter changed for about $100. Since then, the van has continued to improve. My advice, if you are experiencing problems like mine, first make sure nothing obvious in the engine error codes indicate a definite problem. Have the mechanic check all of the likely connections and wires to make sure nothing is melting or become exposed. I really think that I may have figured this one out. At 190,000 miles, I likely never had the fuel filter changed out. My diagnosis is that something in the system that comes in contact with the fuel supply in my engine became clogged up. I put 3 bottles of Rislone into each half tank of gas, and I'll keep doing it until this problem goes away. I'll provide further updates if this turns out to be wrong, but its worth a try! Even an old Plymouth how to book about this 3.3 engine in this model suggested that the fuel supply might be the issue when problems like this arise.
