I have a 03 T&C 3.8 It is missing on three cyliders. It has ran fine before it started doing it. It did how ever feel like there was alot of heat coming out from under the van when it was running ok but that was the only problem i have had with it. Things that i have done so far. Replaced fule filter, plugs oem, wires, coil. Checked for spark on all cylinders. checked ok. If this helps. The plugs that i pulled out of the cylinders that are now missing where very badly warn. There is no mil light on and no frezz frames. I know its running rich by the new plugs have that black powder crap on it. And the cat gets hot and smells like roton eggs.
