Distributorless Ignition Repair

The distributorless ignition enables a longer maintenance interval. We have witnessed cars that don’t need their first tune-up until 100,000 miles. Although the distrubutorless ignition requires less maintenance, they do still require it. For all your distributorless engine servicing needs, call or visit Stonum Automotive today.

Fuel Injection Maintenance 

Fuel injection is a system for admitting fuel into an engine. Since 1990, fuel injectors have completely replaced carburetors as the primary means of getting gasoline into the engine. A fuel injection atomizes the fuel by forcibly pumping it through a small nozzle (under high pressure). Failure of the fuel injection system means poor performance and ultimately destroys the vehicle. Make sure your vehicle’s fuel injection system is maintained properly. For all your fuel injection maintenance and replacement needs, call 303-485-9303 or visit Stonum Automotive today.

Ignition System Repair

An ignition system is a system for igniting (using an electric spark) a mixture of fuel and air in a gasoline engine. A properly working ignition system means a properly starting engine and high performance from your car. For all your ignition system maintenance and replacement needs, call or visit Stonum Automotive today.

Ignition Wires & Cables Repair

Ignition cables also known as spark plug wires are an important part of your car’s ignition system. They transfer the spark from the ignition coil to spark plugs that ignite the mixture of fuel and air. The mixture starts the engine. Over time, ignition wires and cables get weak and break down. This makes it impossible for the spark to reach the engine cylinders. This results in the engine misfiring. The car will eventually fail to start. If it does start, it will run poorly. Common symptoms of faulty ignition cables and wires are: poor gas mileage, engine misfires, engine light is on, and engine may vibrate. If your car needs new ignition cables and wires, call or visit Stonum Automotive in Longmont, CO 80501. Here, you will have the wires and cables changed by a top-rated mechanic.

Spark Plug Change Out

A spark plug delivers electric current to the combustion chamber from the ignition system. Spark plugs that haven’t been changed for a long time can cause ignition problems. At Stonum Automotive, we have automotive experts who will check and replace your spark plugs. For all your spark plug repair or replacement needs, call 303-485-9303 or visit Stonum Automotive today.

Oil, Lube, and Filter Change

To keep running smoothly, your car highly relies on oil, lube, and oil filters. Oil helps in lubricating, cooling, and cleaning the internal engine components. With time, motor oil becomes contaminated. Your car needs an oil, lube, and filter change every three months (or 3,000 miles). When it is time for a lube, oil, or filter change, take your vehicle to Stonum Automotive in Longmont, CO 80501.
