Q: Should spark plugs be replaced early if 1999 buick century is over 18 years old?

asked by on September 18, 2017

should i have spark plugs replaced because of age of vehicle even though it is not yet at 100,000 miles?

My car has 93000 miles.
My car has an automatic transmission.

It certainly would not hurt to remove the spark plugs to take a look at them to determine if they need to be replaced. A normal looking spark plug will have a grayish tan color to the threads and electrode. In some cases the electrode may look burnt with a bit of a pinkish tint to it. In other cases it may be wet or black colored meaning that it may be fuel fouled. I would suggest having a professional from YourMechanic come to your location to take a look at the vehicle and inspect the spark plugs for replacing.
