If the vehicle bucks and stalls and then starts right up, check/replace your crankshaft position sensor. It's located on the top/side of your bell housing. Also check your camshaft position sensor.
I would guess it's one of those two. Start with the crankshaft. It's not uncommon for them to go bad on Chrysler's.

Throttle body is clean. I have kept up with that maintenance.
I replaced the cam position sensor yesterday, and will see what happens there. I have not (yet?) replaced crank position sensor. In reading the service book, the cam position sensor seemed to control spark more so than crank sensor.
I had a previous problem (unrelated to this one) where it was hard to start, but once running, did fine. I found a trouble code that the temperature sensor was bad, and replaced that, and the hard start problem was gone. I suspect maybe similar situation here, where a seemingly unrelated component is going bad, and causes the computer to give a weak or no signal to the coil bank and cause stuttering. But I am guessing.
Thanks for input.
Any way to contact shelleybabee from older post, and find her(?) resolution?

I have replaced the same resistor pack on my 2001 Caravan twice. It went out this morning again! I took an old (bad) one and looked at the thermal fuse (metal bodied part looks like a capacitor) to get the rating. For the record, The OEM part ID for the thermal fuse is MICROTEMP KKJAFW G4A15 TP 128c. I researched Microtemp on the web and noticed that the part is no longer listed on Microtemp's website (if you can call it that). The G4 series is apparently discontinued or just not listed. It is supposed to be rated 10 amps, but I think it's more like 4 amps. If 4 amps is indeed the rating, then it is borderline for a 12v DC motor. The inductive load at turn on is probably what is blowing the thermal fuse. DO NOT DESPAIR! I found a replacement thermal fuse at Radio Shack (of all places). The R/S Part Number is 270-1322 and cost is $1.49 US. It has the same 128 Degree Centigrade rating as the original. The Microtemp Part Number(s) is MNMABM G4A00 TF 128c (R/S Specification says it's 10 amps). I was able to remove the steel shield from the assembly to get to the thermal fuse (use a permanent marker to reference the shield, plastic body, and PC board so re-assembly won't be confusing). Snip the original leads just past the bends away from the fuse body. Place the new fuse (with leads bent to fit in place). Then solder in place. BE SURE TO USE A HEAT SINK BETWEEN THE SOLDER POINT AND THE FUSE BODY! I used 2 alligator clips from R/S PN 270-0346 pack of 10 $ 2.79 US, to heat sink and hold in position while I soldered one side, then the other. Before I re-assembled, I used an ohm meter to verify fuse continuity. After I assembled the resistor pack, I re-installed on the Caravan, and viola it works! I now have several spare assemblies (that I have repaired), and can replace if it happens again. If you aren't very good at soldering, you might be able to find someone that can do this for you (for a few beers Ha Ha). Keep the old assemblies so that you can repair them for future replacements. Total cost for repair was $ 7.26 US. That was for 3 thermal fuses and the bag of 10 alligator clips. Much better than $ 13 US for replacement assembly! Good luck, and I hope you get you fan problem sorted out!! Caravandal.... Suwanee Georgia USA.

Rough Idling slight back fire.

Since the end of winter and the start of spring my 2000 Caravan has been running rough. This happens in the mornings and once the engine warms up it runs smooth. I've changed the fuel filter, air filter, oil change, timing belt (replaced last summer), tune -up (done last summer). I've also added good quality injector cleaner to a full tank of gas. And still it runs rough and sometimes a little back fire occurs. None of my check engine lights come on. Has anyone experienced this problem.

Hi hayneldan.
What and where is the throttle body.
