Idle Talk about Engines (Causes of Rough Engine Idling)

When you slow down at stoplight, your vehicle's idle should be smooth as silk.  But what happens when the engine is missing or idling roughly? That's your engine's way of telling you, "Hey, I've got something wrong with me and if you don't get someone to find out what it is, I may not start the next time you turn the key."

You can help your service facility if you can describe the problem in detail.  Here's a list of things to make a note of:

• When is the problem happening, when the engine is cold or when it's been running for a while?
• Does the rough idling occur when I'm accelerating or when I'm going at a steady speed?
• Does it happen at high speeds?  Does it happen low speeds? Does it happen at both?

Make sure you describe the problem in as much detail because it will help a technician diagnose the problem.

One of the first things they'll check is how the spark plugs are firing.  Modern iridium plugs are supposed to last a long, long time.  But they CAN eventually wear out.  Inspecting the firing end can help the technician figure out the root of the problem.  Corroded or worn out spark plug wires, too, can contribute to an idling irregularity. 

There are other potential problem spots, too.  The technician may check the ignition coil, timing piston rings, valves and cylinder walls. 

If the mixture of air and fuel isn't correct, that may affect how smooth your vehicle is running.  Your service facility is equipped with diagnostic equipment that helps them pinpoint the problem.  Once that idle is smoothed out to the way it used to be, you'll be the smoothest operator on the road.

Follow the Bouncing Vehicle (Bad Struts and Shocks)

If you hit a bump in the road and your vehicle just keeps bouncing up and down for a lot longer time than it used to, you may have bad struts and shocks.  They're the things that help to keep your vehicle's wheels and tires planted to the road surface.

But they don't last forever.  With care and depending on where and how you drive, shocks and struts should be replaced at intervals ranging from 50,000 miles/80,000 km to 100,000 miles/160,000 km.  If you drive on bumpy roads with a lot of potholes, that interval will likely be shorter. Rough surfaces can take their toll.

But how do you know if your shocks and struts are doing their job properly? The best way is to have your vehicle checked by a technician.  He or she can inspect the shock absorbers and struts for leaks, corrosion and damage.  Mounts and bushings can also go bad and they should be evaluated as well.  A thorough examination by a technician will also include looking at other suspension parts. Some may contribute to making your vehicle behave the same way if they're broken, corroded, worn or bent.     

If you need new shocks and struts, your service advisor will make sure that you get those that meet manufacturer's specifications.  That's important because they want to make sure you're getting the handling and performance engineers designed your vehicle to have.

Wash Me, Wash Me Right (How to Wash a Vehicle)

Most would agree they'd rather drive around in a clean, shiny vehicle than one coated with a layer of dirt.  When warmer weather comes around, some of us are bound and determined to wash our own vehicles.  And to protect the paint and its luster, there are a few things to keep in mind when you get out the bucket and soap.

• Cool body.  It's not a good idea to wash a vehicle when the body is hot.  If it's been sitting out in the sun or you've been riding around on a sunny day, make sure you cool your vehicle off by either moving it to the shade or wetting it down with cool water. The problem with washing a hot vehicle is that it's going to dry so fast, minerals in the water can form hard-to-remove spots on the paint.  And some of those can be really difficult to get out.  Best to avoid it.
• Slippery when wet.  Make sure you wet your vehicle down thoroughly before you get the washing mitt out.  Experts keep a couple of buckets of soapy water on hand, and they use soap especially engineered to remove dirt from a vehicle without stripping off the wax that might be on it. 
• The washing mitt.  Experts say to use a mitt with hundreds of moisture-absorbing strands on it.  Start washing at the top and move down.  If you keep dipping the mitt in the buckets frequently, a minimal amount of dirt will stick to it and that will prevent scratching the paint. 
• Wheels last.  Wait until you've finished washing the body before washing the wheels.  Some detailers prefer special wheel-washing tools or brushes. 
• Rinse it well.  Hose the vehicle off thoroughly to get all the soap off, then dry immediately.  Some people swear by a chamois, others like cloth better.  Cotton or microfiber towels will do.  

The next time you have your vehicle in for maintenance, you might ask your service advisor for recommendations on vehicle washing accessories.  They are usually up on the brands that produce the best results.  You may not be a detailing pro, but there's no reason your vehicle can't look like you are.

Unlock the Secret (Malfunctioning Door Lock Actuator)

What a convenience power door locks are on a vehicle.  The latest don't even require you to push the button on the key fob; all you have to do is have it with you.  But sometimes there's a component of power door locks that can fail, especially when they are used several times each day.  Those are called the door lock actuators.

The actuator is an electric part that works with others (like motors and gears) to lock and unlock doors.  You can hear them work, sometimes with the little whirr of the gear or the quiet clunk of the lock finishing its cycle.  And it's good to pay attention to that sound because if it starts to sound different, it could be a signal that your lock is on the brink of failing. Another sign of a failing power door lock actuator is they start working intermittently or quickly and erratically.  The driver's door is often the first to start acting up since it's the one that usually gets the most use.

When you start to notice these signs, consider a visit to your service facility to get your vehicle checked out.  If you wait too long, you may find yourself getting locked out of your vehicle. Many vehicles do have mechanical keys available as a failsafe so you are at least able to get inside.  Some of them are hidden inside the key fob and you should know how to access them.  Check with your owner's manual or ask your service advisor.

It's extremely inconvenient to have to unlock your vehicle with the mechanical key, then get inside and unlock the other doors. It's even more inconvenient if you have passengers in the rear seats.  And that doesn't even count having to go through the same thing to lock the doors when you arrive at your destination.

There are many things that can cause power door locks to malfunction, but if it turns out to be a power lock actuator, the most common remedy is to replace it.  Some are easier for technicians to reach than others, depending on your vehicle's design.  But once your locks are working again, you might think you've found the "key" to happiness!
