I have the exact same problem with my 2003 Marquis. The the sparkplug/coil well was full of coolant and my blue driver sent me right to it. My question is weather there is coolant circulating in that plastic intake manifold.
From post #15
"Coolant does not pass through the entire manifold. Only through the aluminum part (on an original manifold) in the front and maybe the rear. "

Which spark plug hole has coolant?
Is the manifold a replacement or an original?
