Signs That Your Car Engine is Losing Power

There are several reasons why your car engine might be losing power or performance value. Before the modernization of the fuel system, most vehicles were manufactured with carburetors and mechanical fuel pumps. Accordingly, engine power loss was easily diagnosed as a clogged filter or vapor lock. With today’s sophisticated exhaust and fuel system technologies, it can be more difficult pinpointing the underlying cause of a failing car engine.

Engine Power Loss Signs and What They Mean

To ensure you pick up on signs of engine trouble sooner rather than later, keep your eye out for some of the most common tell-tale signs. Whether you experience these scenarios every time you drive or intermittently, it is strongly encouraged to seek out professional auto service to inspect your vehicle for safety and performance issues.

Gas Pedal Inefficacy

If you feel like your gas pedal is not responding at the same rate or in the same way as it used to, it could indicate an issue with your fuel system. The most common fuel system malfunctions are caused by a clogged fuel injector, fuel line leak, gunky fuel filter, or a faulty fuel pump.

Steering Wheel Movement

Does your steering wheel shake vigorously while your vehicle is in idle or coming to a rest? A trembling steering wheel is often a sign of engine power loss, and it typically happens as a result of your cylinders misfiring. What causes cylinders to misfire? Most commonly, spark loss, dropped compression, or imbalanced air-to-fuel ratios.

Poor Incline Performance

Do you notice that your vehicle begins to show signs of struggle as you drive up an incline? If your car slows down as it courses uphill even if you are pressing on the gas, it could be due to a number of underlying mechanical problems. But in most cases, cars that struggle on inclines have a clogged fuel filter. Fortunately, this is a quick an inexpensive repair.

Check Engine Light

If your Check Engine Light is illuminated on your dashboard, it be a warning that your engine is losing power. The underlying issue could be a faulty catalytic converter, mass airflow sensor, O2 sensor, or spark plug wires. Sometimes, the issue related to a defective positive crankcase ventilation valve (PCV), which is a part of the vehicle’s emissions control system.
