Signal in Sound out...

[Pic_User]

I had a compact car, that ran virtually without maintenance, for over 100 thousand miles.

The only problem it ever had:
Sometimes, the engine would "cut out" when I went fast around a traffic circle (round-about). When the engine lost all power the car would slow to almost a stop. Then, it would re-gain power and exit the circle. This happened without regard for weather. There was never any other engine problems.

One day, I found there was a wire (harness) that had been moved, by a mechanic, early in the service schedule. An ignition wire was pulled by centrifugal force, to chafe on the engine. When the chaffing wore a bare spot through the insulation, the bare part would short out, each time the centrifugal force (round-about) would re-appear.

Two cents worth of electrical tape, and back to flying around the traffic circles!

Not that this is any help, I just like telling the story.

I wanted to get back to all of you for your help and encouragement. I ran across a good website for mopar repairs and it seemed to point to several possible faulty sensors. The second sensor I replaced... the MAP sensor, did the job. The faulty MAP sensor was causing the stalling. It hasn't stalled since... over a week now. Thank God it wasn't a harness issue! Ye Gods and Little Fishes!

CUDOS to schu4647. You were spot on!

After years of stalling I have a van running peachie again. *dancing a little jig* (sorry you can't see that... :-)

Again thanks to all.

I don't really deal with the controls side of automotive, but I beleive once a vehicle gets warm it enters a closes system mode. Fuel delivery is then calculated by the engine computer based on the O2 Sensor and MAP sensor. A bad MAP sensor will cause the engine computer to decrease fuel which will cause it to stall. It is all a pain in the but, but it significantly improves fuel economy.
