You definitely have not had the Chrysler update of the computer etc. DON'T DO ITThank you - yes that makes me nervous. I am not mechanical at all so I have a found a shop in Edmonton that will do it all plus completely remove the EGR. I thought about selling the truck, but I've only had minor issues so far. I've only got 70 thou kms on it and simply cannot beat the fuel economy as I do all highway driving with it.
