2009 Mercury Grand Marquis Ignition Coil Packs

 

The 2009 Grand Marquis comes from the factory with one engine: The 2v 4.6L V8. This engine uses 8 individual coil on plugs, which are recommended to be replaced in full sets of 8. You can get away with replacing one if there is a mishap like a coolant leak, or someone improperly washed the engine bay. The coil packs at the local auto parts store can be extremely expensive. You may notice anywhere between $40 and $100 just for one ignition coil. We have the entire set of 8 for the price of one in many cases. On top of that, our ignition coils are the same if not better quality than the other aftermarket ignition coils you may see at the local auto parts store. We include a lifetime warranty, good for as long as you own your vehicle to back our claims up. We not only save you money on the coil packs for your 2009 Mercury Grand marquis. We save you money on the entire process from diagnostic to repair. This is why we include so much useful information on our website to help you repair your '09 Grand Marquis. Keep on reading to learn how to diagnose a misfire in your Grand Marquis without spending an arm and a leg. We will show you how to do this with or without a check engine light on.

 

Diagnosing a Misfire in Your 2009 Mercury Grand Marquis

A simple and easy way to find a misfire in your Grand Marquis is by using a basic OBDII scanner. You can find these online at many retailers for under $20 in many cases. When your check engine light turns on, you can simply plug in your OBDII scanner to get an error code. This will allow you to look up the code online, and find out what the problem could be. For a misfire in your 2009 Grand Marquis, you would typically see something like something like P0301 through P0308. From here, you can swap the ignition coil in question over to a different cylinder to see if the misfire code follows the ignition coil. Of course you want to drive your Grand Marquis for a little bit to allow the PCM computer enough time to recognize the new misfire location.
