Ignition Coils for 2008 Toyota Avalon

 

The 2008 Toyota Avalon uses 6 independent ignition coil on plugs. Each ignition coil sits right on top of each spark plug. These coils are fairly easy to change, but many people's issue with these is the price of these coils. These ignition coils can range from $50-$100 for each ignition coil. We are here to solve this issue. We have the entire set of 6 ignition coils at an incredible price. The coil packs in the 3.5L Toyota Avalon do not have an actual lifespan, but regional weather will affect how soon they fail. Anybody who lives in a humid area will notice that they are replacing their ignition coils sooner than someone who lives in a dry region. Humidity can also expose a bad ignition coil. Even if you live in a dry climate. Remember that when you wash your vehicle, or when it rains, moisture builds up underneath the hood. When this happens, and small issue with the coils will show itself. This is usually a small crack, or a torn rubber boot. Our customers will usually tell us that the misfire started when they washed their vehicle, or during a rainstorm.

 

Replacing all 6 Coil Packs in your Toyota Avalon

Just about everybody in the auto industry recommends that all 6 coil packs be changed at the same time, but not everybody explains why. The main reason to do this is because if one coil fails, and the rest of them are several years old, they are likely to fail soon too. Now if you changed your coils recently, you may be able to change just one, but most of the time this is not the case. Common misfire codes for the 2008 Avalon are P0301, P0302, P0303, P0304, P0305, and P0306. The last number is the cylinder of the misfire. If you are unsure of why your Avalon is misfiring, you can always move the bad ignition coil to another cylinder, reset the computer with your OBDII Scanner, start your Avalon, and re-scan. If the misfire follows the coil, then you know for sure you have a bad ignition coil. If the misfire stays on the same cylinder, then you most likely have a different issue. This will allow you to quickly and easily identify if you have a bad ignition coil or another problem. Check out our how-to section to find out what is required to do this job. This job isn't as difficult as you might think. The firewall side seems difficult, but with the right tools, you can tackle this without an issue.

 

Symptoms of a misfire in a 2008 Toyota Avalon

 

One obvious symptom is a check engine light and a misfire code (P0301, etc), but other subtle not so obvious hints are occasional hesitation. If you feel the engine hesitate here and there, it could be a misfire. The feeling is very distinctive. You will certainly feel the engine miss a beat. This usually happens when putting the engine under a load (accelerating, uphill driving, etc). Using your OBDII scanner to scan the check engine light is one of the best ways to avoid the auto shop and save money. If you don't own an OBDII scanner, GET ONE! They are cheap and they will save you a TON of money. We just started to notice that the local stores have basic scanners for $20. If you are more savvy, you can find one online for under $10.  Another easy and free way to check for a bad coil pack is to pull the vehicle into a dark space like a warehouse or garage. Turn all the lights off, and let the engine run (Make sure that the exhaust is ventilated!) and look under the hood. If you have a constant misfire, you may be able to see the spark arching out. You may need a small mirror to check the coil packs on the firewall side, but you will still be able to see them.
