What about the engine timing?

If the vehicle’s engine has low performance and/or there’s poor gas mileage, the ignition timing may need adjustment. The four stroke automotive engine requires that a number of events happen in a precise sequence and at a precise time.

How do I know if the timing needs to be adjusted?

If the timing mark on the main crank pulley lines up properly to the degree tab on the front of the engine, the ignition timing is correct, and no adjustment is necessary. Although not necessary, some auto professionals recommend replacing spark plugs and wiring when adjusting the igniting timing.

What are my options?

The vehicle can be taken to an auto or repair shop, or a skilled owner may be able to adjust the engine timing, dependent on the make and model. There are several automotive websites that offer free DIY instructions. Other vendors advertise repair services or sell repair kits and parts, and service manuals or how-to books can also be purchased online.
