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.
If your vehicle is showing symptoms such as dim lighting, "dragging" during engine starts, or frequent dead batteries, then the charging system may be at fault. Although it may seem obvious, the first item to test is the battery itself. A defective battery in an otherwise healthy electrical system can cause any of the above mentioned symptoms. Testing the battery is a simple procedure, and can performed quickly by most auto parts stores, repair shops, dealers, and even some large department stores.
