Plugging Away (Spark Plug Replacement)

If you drive a vehicle with a gasoline engine, thank the spark plugs for igniting the gasoline/air mixture in each cylinder that keeps your vehicle traveling smoothly down the road every day.  Your spark plugs work hard, firing thousands of times in a well-choreographed order, and you usually don't pay much attention to them until one of them stops working the way it should.

Signs that spark plugs are wearing out include:

• Engine runs more roughly than it did
• Vehicle doesn't start as easily as it used to
• Vehicle hesitates when you press on the accelerator
• Your fuel economy has gotten worse

When a spark plug stops working altogether, you will find your engine has likely lost a lot of its power and isn't running smoothly.  Your Check Engine light may  come on.  Then it's time to head to come to our service center to have it diagnosed.

If your plugs need to be replaced, they're usually done all at the same time. And if your vehicle has spark plug wires, experts recommend you change them as well. Different type of spark plugs last longer than others, and your service advisor can discuss what's best for your vehicle and driving habits.

A technician will also determine if there are any carbon deposits on your plugs, how healthy the ignition coil is (it's the part that supplies the high-voltage jolt that makes the spark) and will look for other signs and symptoms that may point to other problems in your engine. For instance, if a spark plug is fouled by oily deposits, it's possible oil is getting into the combustion chamber. 

They will also check all the plugs to see if there are problems in just one or all cylinders.  Sometimes a technician will find a plug that has overheated, literally melting the metal.  In that case, they may recommend they correct that problem before replacing the spark plugs.

Most spark plugs will last for a good, long time.  Even if you aren't seeing any symptoms they're wearing out, make sure you have your service advisor check your vehicle manufacturer's recommended maintenance intervals.  Preventative maintenance will keep your vehicle running reliably so you can count on it to get you where you want to go.

Stuck! (Vehicle Door Issues)

This may have happened to you.  You drive somewhere and get out of your vehicle only to try closing the door and it just won't stay closed!  What a helpless feeling.  You can't lock it; you can't leave it like it is. Or, let's say you head down to your vehicle to head out to work in the morning and you can't open the door.  What are you going to do now?

Vehicle doors take a lot of abuse.  They are opened and closed hundreds of times and we expect them to just keep working perfectly all the time.  They do require a bit of tender loving care.  Let's take a look at two different scenarios of stuck doors.

First: the door that won't close.  It's a security issue.  It's also a safety issue.  You can't really safely drive a vehicle with a door that won't close. What if you or a passenger is tossed out?  Sure, some people try to tie a stuck-open door closed or bungee it, but that's dangerous.  It's best to get that vehicle to the service repair facility as soon as you can, and having it towed is the safest way. 

Second: the door that won't open.  There are many reasons this can happen.  Freezing weather is one, a misaligned door is another.  There could be electrical issues.  Corrosion could have broken a part inside the door.  The possibilities, unfortunately, are numerous.

If you can't get into your vehicle's driver's door, with any luck another door might open and you can climb into the driver's seat and head on to the repair facility.  A lot of people may be tempted to try to fix a stuck door themselves, but many wind up causing more damage to the door and have to have a trained technician step in to repair the mess.

One way to minimize the possibility of having a door stick open or closed is to make sure it gets regular maintenance.  Door locks, hinges and latches should be lubricated at certain intervals.  Locks should be kept clean.  While many vehicles now have electronic locks, sometimes an electrical failure in the vehicle or key fob can inadvertently lock you out.  Nearly every vehicle has a mechanical key in case that happens; if you don't know how that works, have your service advisor show you how. 

Also, you technician can make sure your doors are properly aligned and aren't sagging. All of these things can help you keep your doors opening and closing the way they were designed to. Your next trip may "hinge" on your doors being in top condition.
