Plugging Away (Spark Plug Replacement)

Posted May 7, 2023 9:07 AM

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.

Very impressed with Han's Imports. Did a nice job with maintenance on my BMW and my wife's Benz. I also appreciate the thorough check of the rest of the car as part of their 1st look at the cars. I'll be back. quotes-image

Anyone who dumps on this auto repair shop should literally start driving a horse and carriage. What people don't understand is that when you bring in older import vehicles from the north east United States they are prone to rust deterioration do to climatic factors. As a result, many parts are harder to replace, many need to be fabricated and even more common is the rarity of older European models (which drives the price of parts up as well as renders low availability). I've been an automotive repair technician (ASE certification, various big name certifications and even fabricated parts whilst working in small shops) for quite some time. As well, I've even taught Automotive Repair as a core coarse at the secondary level. All of that said, I'm quite certain my opinion holds merit. Thus, I can honestly say that Omar is an absolute genius. I run a small shop in a rural area and seek advice from the owner of Hans Imports (Omar). This goes beyond the scope of older European models. I often probe Omar for repair strategies, knowledge and diagnostic information on newer Imports. For what its worth, you're in good hands with Hans Imports in North Kingstown. Any of the negative cockamamie complaints are clearly the result of someone thinking they are above the knowledge, experience as well as expertise of the working man!quotes-image
