SOURCE: own a 1997 mercury grand marquis. went to change

The 4.6 does not have an traditional distributor. This year engine should have two coil packs located on the front of each valve cover. Each coil pack controls four cylinders. Some of the plug wires will cross over the front of the engine in a wire loom on top of the alternator. The spark plugs are located down in the intake manafold. they run beside the fuel rail on each side of the intake manafold where it joins to each head. You will need an extention at least 8 to 10 inches long to get at the spark plugs. The plug wire fit snuggly into the intake manafold and have an extention on them that connects to the spark plug.

2001 mercury grand marquis reading code p305 misfire, spark plugs and coils changed

Try putting the old coil back & walking the new one to

driving to get it fix,but better than a shop guessing, because

Where are the spark plugs located on a 2000 Mercury grand Marquis?

There are eight COPs (coil-on-plugs) to remove. Using a 7mm or 9/32" socket, remove each bolt securing each COP to the intake manifold on top of the engine. Remove all eight COPs, and the spark plugs are underneath. When replacing the spark plugs, use only the proper Ford/Motorcraft plugs, even if they cost twice as much as the aftermarket ones. You will avoid further headaches this way. Hope this helps.

2001 mercury grand marquis. Engine stutters or hesitates with jerking when lightly accelerating. Seems like an air, fuel, or spark delivery problem. At wide open throttle this problem is not as noticeable....

Start car and use a squirt bottle of water to wet the wires and coil, if you see it spark or run rough one or both are bad, repair the wires first as they are more common.

Is the engine a glow plug or spark plug engine

This engine is a gasoline engine, so it used Spark Plugs, only diesel engines use Glow Plugs as an aid in starting.
