1996 Town and Country Momentarily Cuts Out

Hope someone can give me some clues - this seems like a tough one.

It's a 1996 T&C with 3.8L V6

The engine cuts out for very short periods. Most of the time it's
just a very quick hesitation for less than a second and the engine
keeps going. Other times it dies. Almost always starts right up on
the first try. This usually occurs after the engine is warm. Then
the "events" may happen every couple minutes or so. This has been
going on for a few weeks and seems to be getting worse. There's
usually not a problem until the engine warms up.

Seems to be an electrical problem. On a hunch, I rigged a light to
the fuel pump (green/white wire) and put it where it could be seen by
the driver. When the engine cuts out, so does the light. But I'm not
convinced that the problem is related just to the fuel pump circuit
because the engine cuts out at the same time as the light. Wouldn't
there be tiny delay, and sputtering if there was just a fuel pressure
drop?

During cut outs, the Speedometer still works.

The check engine codes are 12 61 55. I'm guessing that the 61 (Baro
Sensor Open or Shorted) indicates a bad MAP sensor or vacuum leak or
something? But maybe not related to the engine quiting.

I've fiddled with all the connections I could find, to no avail.

An old message in this group suggested replacing that cam position
sensor, but this didn't make any difference in the behavior.

Any ideas??? Thanks, Dave.

 

your code 61 could be a clue to a shorted engine wiring harness or a
corrioded wire.since the ground circuit for the engine sensors are shared
on the same wire
i would check it with a fine tooth comb and also get bcm fault codes
pulled
tose might lend a clue to solving your issue
