Im still working on this, The PCM cannot correct this problem. The codes don't mean much to the average person. They give you an idea where to start looking. Maybe a bad fuel injecter, bad cam sensor etc.

Check the engine sensors. I changed all the engine sensors on my 1996 Dodge Ram Van and it vehicle only started when I changed the Flywhel sensor on the bellhousing and it was also the cheepest sensor to buy. My auto mechanic scanned the on board computer but this did not show up the problem sensor. he had a spate of Chrysler group vehicles in with this same problem and it turned out to be the Flywheel sensor and for some reason Chrysler do not put this sensor into the on board computer checking system and did not show a fault code on the OBD.
