The van stalls without notice at times when ready

A bad vacuum line will cause this code also. Also it will cause a rough idle and stalling. Open the hood and listen for a hissing sound. track it and you,ll find the leak. Also I would just check all the lines to make sure another in not ready to go.

take a little time to check the air/fuel filters and spark plugs if you have not done so in a long time. all of those things will cause the van to stall at light or stop sign. replace all items that need replaceing. a little service work will keep your van running for a long time.

because they only made 3.8 for that year

Have fuel system (injectors) and throttle body cleaned. Belt is OK most likely.

This has happened on our van multiple times. Through some internet searches I have found a solution that works.

Go to your van and, with the ignition off, press and hold the trip reset button. You will see 'Sof' and perhaps some diagnostic test numbers will show up on odometer; the unit will perform a self-test, and the system will do a reset and should it should operate normally.

Cheers!

i have the same van (2003), same problems, the deler just replace my PCM cost me $950 van works fine untill now.

Check the sensors on the throttle body. There is a sensor that controls air to fuel ratio. If that sensor is bad then the car will run and then stall out while in drive. I had the same problem when it was cold outside last winter. If you dont want to dish out the money without knowing if it is that part at fault or not then start the van pop the hood and located the throttle body. Place your hand on the sensors and give them a little shake and then make sure they are plugged in all the way. You could also turn the van off and unhook the sensor clean the connectors and plug it back in. That should do the trick and if it doesnt stall anymore then I would replace those sensors if I was you. One more thing. If your giving the sensors a tug while the car is running and you hear it going to stall you could located the gas pedal cable and give it a rev or two by hand so it doesnt stall out and turn off. By the way. You van isnt over heating at all is it?

if it stalls and start right away without long crank time more likely you have ignition spark cutting out.this vans are notorious for ecm failing to ground contorol.if it is a 3.3 or 3.8 V6 very common problem. check for spark at a plug wire when stalles and if no spark replace ecm.i hope i was helpful. please rate me.

adjust idle speed

YOu should be able to tell if coolant leaks caused the coil pack to fail. I believe it is 2 issues.
