Having problems with your 2003 Dodge Caravan ?
What happen when pcm starts to go bad - 2003 Dodge Caravan
Not sure exactly, but I just replaced mine about 5 days ago. Mine was driving along fine and suddenly started sputtering and stalling out. Would only go about 30mph, wouldnt shift out of 1st. It was blowing black smoke out the exhaust. I had a mechanic diagnose it as being a bad computer. After I replaced it, I still had the same problems. After further research I discovered that a common problem in the 2003 caravans is the fuel rail harness. (connects the injectors to the main wiring harness) Right where the two harnesses connect, the wires are right above the intake manifold. The wires melt and short out. Hope this helps.
