i had asimiliar misfire on my 2000 windstar.the first thing to check is a broken valve spring by taking off the valve cover the other is a o2 sensor bank 2 i believe is the downstream.if not the valve spring then either the coil pack or thecontrol module. either way it is fairly inexspensive

You can't do it with out a tech 2 scanner, so your going to have to go back to the Mechanic to have it reprogrammed. As long as it's running rich, your going to have bad fuel economy and will not pass the emission test when you have to have it done. Good luck and glad to know you got your car running almost 100%
