A simple tune-up can help your performance and fuel economy while helping you minimize your repair bills. A tune up can be performed by nearly anyone in a single afternoon..
Step 1). Replace your spark plugs.-Fouled, damaged and otherwise worn out plugs cause numerous engine problem. Change your spark plugs one at a time to avoid "cross wiring your plug wires. It is good practice to change your spark plugs every 30,000 miles,check your owners manual for your specific interval.
Step 2). Replace plug wires- Ā Plug wires are often over looked when doing a home tune up, since they rarely show any wear. Replace your plug wires one at a time and route the new wires the same way as the old ones. The routing of the wires is important to insure no interference with other electrical systems. Plug wire break down internally and loose conductivity causing hard starts,stalling misfires.
Step 3). Replace air filter- A dirty air filter can cause you to loose power and fuel economy. When your engine can't breathe properly it works harder and uses more fuel.
Step 4). Replace the other filters- The smaller often over looked fuel filter, PCV valve, and the breather element all have a major impact on performance and dependability of your engine.
Step 5). Replace your O2 sensors- The oxygen sensors are the number one reason for failures of "smog tests". The O2 sensors are also at fault for rough idling, surging and hesitation. The O2 sensor will require a specic socket wrench made for the specific vehicle that you own.
Step 6). Clean the fuel system- A simple step such as adding a fuel system cleaner to your vehicles gas tank during your tune up can really pay off in the long run. deposits and gum in your fuel system will cause a number of problems and worsen any you may already have.
Step 7). Change your oil and filter- This could possibly be the most important step you can take to insure the life of your vehicle. Both easy and inexpensive there is really no excuse not to change your oil and filter. The oil in your engine is not only for lubrication but is also very important to cooling the engine.
