I'm not sure about your issue but since I changed the camshaft sensor my hasn't stalled once. Good luck

 

Thanks for the suggestions. I haven't heard any noise from the bellhousing area, but I'll try to take a closer look at the flex plate.

BigBlue, my van has the 3.0L with the cam sensor inside the distributor - not sure if I have to replace the entire distributor or if I can change the sensor only, and how difficult it would be?

 

Just wanted to tie this one off. It was indeed the Cam Sensor. Had to replace the entire distributor but the van runs great now (maybe too good - seems the tranny is slipping a bit but I didn't notice it before because I thought it was part of the engine issue

So I'm still trying to wrap my head around this: The cam sensor gave no code, but was still sending a signal, it was just wrong. I think the PCM uses the signal to determine injector timing, so the cylinders would get get fuel at the wrong time. I guess it stalled on acceleration from idle and coasting because it was fuel starved when I opened up the throttle?

The other thing is, even without a code, with my scanner I could figure out if just about every other component was sending a reasonable signal (TPS-%, MAP-mmHg, O2-v, Crank sensor-rpm, etc). But I still can't see any way to tell if the Cam sensor is sending a flaky signal - all I saw was fuel trims being out, etc. I just replaced it because I was out of ideas and others on the board had luck replacing theirs. Is there any way to analyze the cam sensor signal using a scanner?
