remove the coil packs on top the engine with a small tork bit then change plugs
The Concorde could misfire for several reasons. Start by checking for proper fire to the spark plugs. Then check engine compression to see if a cylinder compression is down.
Looking at the top of the engine. Look between the runners of the intake manifold and you will see six square black boxes all held on by two star head screws. Remove the screws and pull up the coil boxes, under these are your plugs. Use a deep socket to change the plugs.
engine needs to be removed
under the coil paks on the valve covers
The freeze plugs are on the engine, not the transmission.
From the top you will need to remove the wiper module and have a cold engine. You can also remove the plugs from under but you will need a lift and cold engine.
There are freeze plugs on the left, right, and rear.

I reach over and around the top of the engine to access the spark plugs.I reach over and around the top of the engine to access the spark plugs.
Easy job, they are located under the coil's. Disconnect the coil primary wire connector then using a torx bit remove the two screws holding the coil to the valve cover then lift the coil from the engine and remove the spark plug.There are no spark plugs on this engine.
The engine seemed to be missing/chugging when we hit around 80 - 100 km per hour and the engine light came on. This is a huge sign that you need to change your spark plugs and any bad coils.
