Chrysler Repair Questions? Ask a Mechanic for Answers ASAP
Hello and welcome to just answer.
There are 3 common causes for this. 1 a failing crank shaft position sensor, 2 a failing cam shaft position sensor, and 3 a failing PCM (engine computer). Either one can act up when the engine warms up. Do this: try to get your van to an auto parts store like AutoZone and ask them to connect their OBD 1 scan tool (not OBD 2) to your vehicle and check for any trouble codes. If there is a code for "loss of crank sensor signal or cam shaft sensor signal" then have the appropriate sensor replaced. If there are no codes at all, then suspect a failing PCM and have it replaced. Most auto parts stores will connect their scan tool for no charge to you. I don't think it is a map sensor.
Hope this information helps, and let me know if you need more assistance with this.
