2003 Mercury Grand Marquis Ignition Coil Packs

 

The 2003 Mercury Grand Marquis will run great if all of the ignition coils are operating properly. If one goes bad, you can get a misfire, and a check engine light. Sometimes you may get a flashing check engine light, which means that the problem is immediate and must be taken care of before damage occurs to the catalytic converter. There are also times where an ignition coil is in the beginning stages of failure. This will cause a misfire while trying to accelerate, but your 2003 Grand Marquis will still drive smoothly while you are cruising. Many times the check engine light does not turn on either, which makes it difficult to identify where the misfire is coming from. We help you to identify the misfire locations with our helpful how-to guides. Araparts is committed to providing not just low priced quality auto parts, but we also want to save you money on the entire process. Many customers ask us how we can get our parts so cheap. We don't offer cheap auto parts by lowering the quality. We do this by purchasing ignition coils in large bulk , and cutting the middle man out. Many auto parts stores have DG508 ignition coils for your 2003 Mercury Grand Marquis for prices that are simply too much. We have seen these run all the way up to $100 for just one ignition coil. 

 

2003 Mercury Grand Marquis Ignition Coil Pack Replacement

 

If your 2003 Mercury Grand Marquis needs the ignition coils replaced, you can do this at home if you are somewhat mechanically inclined. All you need is a ratchet, a 7mm socket, and at least a long and short extension. A swivel socket will help, but is not necessary. First remove the debris from around the ignition coils This can be done with a rag if you don't have access to compressed air. Then remove the 7mm ignition coil bolt. Move the coil around the fuel rail and lift up and out. It may be helpful to grab onto the ignition coil from the rubber boot as these can sometimes get stuck. If the boot comes off, you can simply pop it back on. If you have not diagnosed the issue yet, then all you will need is an OBDII scanner. These tools can be found on many online retailers for under $20, and they will be one of the best investments you can get for your Grand Marquis.
