Is Your Porsche Cayenne Shaking When Accelerating? Here are Some Reasons

Shaking of the vehicle while accelerating or normally driving is a very strange sign that can surely make many people to worry. Especially the owners who have purchased such high quality cars but their car gets such strange issues. If your Porsche cayenne shakes or jerks while accelerating, then this article is for you. In this article, you’ll gonna know about the top reasons behind the jerking of Porsche cars when they accelerate.

Reasons behind shaking of your Porsche cayenne

Mostly, the problems is engine causes shaking of vehicle while accelerating. The vehicle runs roughly to produce a little amount of power and also produce noises. Here are some common reasons behind the shaking while accelerating in Porsche.

Ignition system issues

Faulty ignition system have issues in ignition coil or spark plugs which cannot burn the fuel in the cylinder. Due to inappropriate firing, it leads to misfires and the engine jerks.

Fuel delivery system issues

Fuel delivery system delivers the fuel to the engine cylinder. If the system has some damage or any blockage then the fuel would not reach the engine in correct amount. These issues consists of damage of hoses and gaskets which cause leakage of fuel and low fuel pressure. Clogged fuel filters and fuel injectors do not allow the fuel to enter to the engine. So the lack of fuel or lack of pressure in fuel causes problem during combustion and the engine shakes.

Faulty exhaust systems

The exhaust systems performs the work of removing the exhaust gasses that are byproducts of combustion out of the vehicles. By removing the exhaust, it enables the engine to take fresh air from air intake system. The exhaust system enables the engine to breath. But exhaust systems have a catalytic converter which get clogged with dust from exhaust. This blocks the exhaust system to remove the exhaust gas from the car. So the engine also stops to take fresh air due to which the engine cannot perform the combustion properly and begins to shake.

Issues in air intake system

The air intake system takes air from the surrounding and supplies it to the engine and the cabin. Air intake system is responsible for supplying correct amount of air to burn the fuel properly, just like fuel intake system supplies proper amount of fuel to the engine. In combustion system, the air and the fuel ratio should be in a proper ratio in the air-fuel mixture for proper combustion process. These systems work in such a way that the ratio of air and fuel in the combustion chamber remains 14.7:1. But if the air intake system malfunctions, then the ratio will be affected. If the air from the air intake system becomes much more, then the engine would run lean. If the proportion of air becomes too low, then the engine would run rich. In both the cases, the engine would shake, because the combustion process would not go well.

Unbalanced and misalignment of wheels

Problem at the wheels can cause shaking. If the wheels are worn unevenly or damaged which shifts the center of gravity of wheel away from the axis, then the wheels are said to be unbalanced. Even some brand new tires have some imperfections which can make the wheels unbalanced. Such unbalanced wheels when installed in cars and it rotates it shakes the whole vehicle. If the wheels are not properly aligned, then it can cause shaking as well as pulling the car to one side while driving.

Loose lug nuts

If the lug nuts of a wheel are loosened then it would cause shaking at the wheel while driving. The shaking may become worse if you accelerate the car.

Low pressure at the tire

If any of your car tires has a low pressure than the required pressure. Then your car would also vibrate at high speeds. Have your tire pressure checked at the auto service center.

Conclusion

If you are having jerks is your Porsche cayenne then you should not delay in diagnosis. Have your wheels checked and then your engine at the Porsche service center.
