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.
Alternator: now this was a breakthrough!! Before the alternator was the dynamo-machine. A DC generator who wasn't that bad, but had a lot of glitches, the regulator system was complicated, it was large and in some cars highly unreliable. Then came the alternator. It was brilliantly constructed, highly dependable, half the size of the dynamo and very easy to repair. The output that it gave was much more stable and consistent thus allowing more appliances to be put in the car.
