2005 Caravan, what engine? Has oil been changed lately? Is there any problem with performance, such as stalling, stumble, hard starting or anything abnormal happening?

Do not shut off the Van and check the lights.... Did you have your Transmission serviced lately? Common problem with this transmission.

Your problem could quite possibly be an internal issue with PCM/ECU

No Only chain.

Cycle the key on, off, on, off. on. Then count the flashes 12 is normal 55 is end of sequence

power wire is grounding out somewhere,check the wire,look for kinks,shaffing, then unfortionatly it could be in the fuel pump, it;s gas,,if it's grounding,,arcking somewhere??? i shouldent have to say the rest,,, good luck

WHEN SERVICE VECHICLE LIGHT COME ON.THE DEALERSHIP HAS TO CHECK OUT EMISSION CONTROL SYSTEM.MAKE SURE ALL EMISSION COMPONENTS IS WORKING PROPERLY.THEN THEY HAVE TO RESET SERVICE VECHICLE LIGHT WITH A SPECIAL SCANNER.

You can take the van to Autozone, they will test the check engine light to be sure. More than likely you have a bad plug wire or plug. If a plug is not firing right it will not burn the gas, hence your rough idle and back fire.
