As the lifeblood of every functioning vehicle, the engine needs to run smoothly. If unfamiliar with common problems that can arise with the engine, its maintenance can seem intimidating. Fortunately, certain problems seem to arise more often than others, and not all require expensive repairs. Here’s a list of the most common engine issues and a strategy for avoiding them.
Responsible for checking and balancing the air-fuel combination in the engine, oxygen sensors are essential elements of modern vehicles. With a faulty oxygen sensor, you might see a rough idle, lowered fuel efficiency, engine misfires, or decreased performance, and this issue will often cause the check engine light to come on.
A car’s ignition coils send electrical signals from the computer to the spark plugs, which in turn ignite engine fuel to allow the car to start. A malfunctioning coil might cause engine failure, rough idling or a stall, and prolonged trouble can cause further damage to the engine.
Although failing spark plugs can be expensive and labor intensive to replace, their failure has distinct warning signs, including rough idling, misfires, decreased acceleration and high fuel consumption. If you see any of these signs, have the vehicle serviced immediately. To avoid excessive wear and tear, most manufacturers recommend having spark plugs replaced every 60,000 – 70,000 miles.
As an emissions component, the converter heats unburned particles in the exhaust and is comprised of metals like rhodium, platinum or palladium. When this part fails, the engine produces a foul odor and can also cause misfires. Although catalytic converters are made to last for the life of your car, ignoring regular maintenance can exhaust other components and lead to converter failure.
Mass Air Flow Sensors
This sensor helps maintain combustion in the engine’s computer by measuring the air that passes through and relaying this information back to the engine. Thus, the engine knows how to determine how much fuel is needed for optimal combustion. Unfortunately, the mass air flow sensor can malfunction at any time, so having a professional examine your vehicle if you notice rough idling or excessive gas consumption is your best option for early detection.
A Common Solution
As always, regular maintenance and heightened attention to your vehicle’s performance are the best ways to catch a problem early and avoid engine failure. Since this is a complex component of your vehicle, having a professional diagnose and repair any issues is recommended.
