Among the various luxurious cars that one gets to see on the road Mercedes is a class apart from the rest of the automotive brands. The popularity of Mercedes can be gauged from the number of these cars that one gets to see on the roads of Kalamazoo.

However, owning a Mercedes comes with its own set of challenges in the form of regular maintenance & service. Despite your best efforts issues with your Mercedes will crop up and one such common problem reported by most drivers is related to the Mercedes shaking while idling.

Rough idling is a common problem affecting most high-end cars and your Mercedes is not exempted from this problem. Here in this article, we will discuss the reasons behind rough idling in your Mercedes.

Dirty Fuel Injectors

One of the prominent reasons behind your high-end car experiencing rough idling is due to dirty fuel injectors. The fuel injectors are responsible for providing the engine with pressurized fuel that helps in the efficient combustion process of your vehicle and also makes your car fuel efficient.

However, with years of running the fuel injectors are subjected to high temperatures and the tiny nozzles through which the pressurized fuel is delivered tend to become clogged up with carbon deposits from the combustion process.

This is when the fuel injectors start to have issues and your high-end car gets inadequate fuel delivered to the engine which leads to an incomplete combustion process. The incomplete combustion often leads to various issues and due to this; you might experience rough idling in your vehicle.

Blocked Air Filter

The air filters are one of the most important components in your vehicle that prevents the entry of dirt and debris into the engine. For the smooth running of your car, the air-to-fuel ratio must be perfect and most of the time problems with the air/fuel ratio lead to issues with the running of the car.

With years of usage, the air filter of your car tends to get clogged up with dirt and debris and this causes insufficient air to enter the car and leads to shaking of your vehicle when you idle. Often problems with the air or fuel delivery to the engine either cause your car to run ‘rich’ or ‘lean’.

This is why it is often advised to inspect the air filter of your car regularly so that they can be cleaned to prevent them from getting blocked. Often people have to replace their air filters and if your luxury car needs one, then get in touch with a Mercedes specialist for replacing the air filter.

Worn Spark Plugs

The spark plugs are an integral part of the ignition system and provide the intended spark to ignite the air/fuel mixture in your car. Most of the time vibrations while idling are caused due to worn or faulty spark plugs in your vehicle.

Whenever the spark plugs start to wear out or become dirty, they fail to provide any spark to ignite the fuel located inside the cylinders of your engine. This is when you will get to experience engine misfire and often you might get to feel the vibration of your car while idling.

Most of the time dirty spark plugs once cleaned begins to function without any hindrance. However, if you are still facing issues with your car, then you must replace the faulty spark plugs.

Malfunctioning Fuel Intake System

Most of the time the vibrations you experience while idling comes from the engine of your car. Now, the shuddering of the engine shouldn’t be taken lightly because this indicates something is seriously wrong with the fuel intake system of your car.

As your high-end car starts to accumulate miles, the fuel intake system begins to age and also gets dirty. Often it is seen that the fuel injector malfunctions when the valves become clogged with dirt and debris. Clogged valves are not able to supply clean fuel to the engine consistently.

This is why you experience the shaking of the engine when idling. In addition to inspecting the fuel intake system, the mechanic will also have a look at the fuel pump of your car to rule out any issues with its functioning.

Finally

The above-discussed factors are some of the leading reasons behind your Mercedes shaking when idling. Most of the time people tend to ignore the issue & this leads to additional damage to the car. Whenever you experience anything wrong with your Mercedes, then take your luxury car to a certified repair shop for getting it diagnosed and fixed.
