What Causes a Muffled Sound from the Car Exhaust Pipe?

[SanKyle]

The muffled sound from the car exhaust pipe is caused by poor spark plug ignition or excessive carbon buildup in the intake manifold. It can be resolved by disassembling and inspecting the components for repair. Below are some important driving precautions: Right of Way: At intersections controlled by traffic signs and markings, yield to the party with the right of way. At intersections without traffic signs or markings, stop and look before entering, yielding to vehicles coming from the right. Turning vehicles must yield to vehicles going straight. For vehicles approaching from opposite directions, those turning right must yield to those turning left. Prohibited Actions: Vehicles are prohibited from reversing in railroad crossings, intersections, one-way streets, bridges, sharp curves, steep slopes, or tunnels. Vehicles may make a U-turn at locations without no-U-turn or no-left-turn signs or markings, provided they do not obstruct the normal passage of other vehicles and pedestrians.
