Mitsubishi Lancer Feels Underpowered and Makes a Muffled Sound When Accelerating?

The first issue is caused by abnormal fuel combustion. You need to clean the throttle body and fuel injectors to resolve it. Take the car to a repair shop to read the data streams of various engine sensors for troubleshooting. The second problem is caused by resonance. In this case, first check if the tire pressure of all four tires is within the normal range, then inspect the chassis for any impact damage or deformation. Also, check if the ball joints and shock absorbers are leaking oil, and if there is excessive play in the wheel bearings or half-shafts!
I've experienced the Mitsubishi Lancer feeling sluggish and the sound being muffled several times, mostly due to issues with the fuel system or intake. For example, using low-quality gasoline can clog the fuel lines, leading to insufficient fuel supply; or if the air filter accumulates too much dust, it can't draw enough air, resulting in weak power. A muffled sound often indicates a clogged exhaust pipe or catalytic converter, causing a droning noise due to poor exhaust flow. It's recommended to check these areas first, try replacing the filter, and cleaning the throttle body carbon buildup can significantly improve the situation. Avoid long-distance driving to prevent damage to engine components—safety first by visiting a nearby repair shop for inspection. Regular maintenance, using good fuel, and periodic cleaning of parts can prevent similar issues from recurring.
