How Do You Know When You Need A Tune Up

How Do You Know When You Need A Tune Up – If the engine misfires, hesitates, joints, gets poor mileage, is not easy to start out or has failed an emissions test, it evidently needs something, though a tune-up in the traditional sense might not be the cure. In the event you tell a repair shop you desire a tune-up, the mechanic should ask why you feel you will need one before recommending any service. Just like a doctor should ask what symptoms you’re experiencing, a mechanic should seek to diagnose the problem. And simply as a doctor may recommend some tests, a mechanic may do the same. You may speed the process by being all set to describe what happens and when (such as whether your car hesitates when the engine is frosty or when passing at highway speeds), any noises you hear and what you feel when your car’s “illness” shows up.

One caution about lower fuel economy: You should proceed with the expectancy that it will go down at least slightly during the cold a few months, and maybe a whole lot. Colder temperatures make your engine and charging system work harder. In addition, winter gasoline blends have slightly less energy content than summer blends, so they don’t deliver as many miles per gallon. A tune-up won’t make Old fart Winter, or his effects, go away. A misfiring engine (when ignite plugs ignite at the wrong time) could be caused by worn or fouled spark plugs. Negative spark plugs can also cause low gas efficiency, hard starting and slower acceleration. Most plugs, though, should last 100, 1000 miles or more, and engine computers do an impressive job of compensating for worn plugs, so that might not be the key or only culprit.

A dirty or clogged engine air filter is more likely to lower acceleration than fuel economy, according to tests conducted by the EPA. Because filters get dirty little by little after some time, you might not notice a tiny but steady loss of performance until your car is accelerating such as a turtle. But if you haven’t changed the filter in a couple of years (or sooner in areas that contain a lot of soot in the air), that could be part of the problem. Engine deposits caused by lower-quality or contaminated gasoline create drivability problems, and the cure for that might certainly be a fuel system cleaning, either by a repair shop or with a gas-tank additive.
