From the first steam powered coaches to today's super-cars, an automobile is a vehicle that undergoes constant changes and improvements. The first cars that were invented could barely replace the horse, were not reliable and didn't show any promising future. But people who were visionaries kept the idea alive, pressured forward thus making the car a irreplaceable part of our lives.
What are the signs and symptoms that might make you think your vehicle needs a tune-up? A misfiring engine (when spark plugs ignite at the wrong time) could be caused by worn or fouled spark plugs. Bad spark plugs can also cause low fuel economy, hard starting and sluggish acceleration. Most plugs, though, should last 100,000 miles or more, and engine computers do a remarkable job of compensating for worn plugs, so that might not be the main or only culprit.
