Why Does My Porsche Take Too Long To Accelerate?

Your Porsche worked fine barely 24 hours ago. But suddenly, it does not accelerate like it used it. In other words, it takes too long for it to pick speed. This irks you so much because you cannot tell where the problem is. This means you do not know how much it will cost you to repair whatever is faulty.  Truth is, there are so many reasons why a Porsche can suddenly have a hard time picking up speed. You do not have to worry because in many cases, the problem is something you can fix without spending too much. Here’s why your Porsche is taking too long to accelerate and what you can do to fix the problem.

Clogged Mass Airflow Sensor

Otherwise referred to as the ‘meter’, the mass airflow sensor is attached to your Porsche’s inlet air cleaner. Its main function is to air mass that flows into the air intake. This may appear like any other car function but it isn’t. Modern Porsche models have automated diagnostics that make it easy for the computerized system to capture and measure the amount of air mass that flows into the intake. A clogged or faulty air mass sensor will therefore send the wrong data to the Porsche ECU. The end result is a car that won’t accelerate correctly. Fixing the air flow sensor is as you may have already guessed, the only solution here.

Faulty Oxygen Sensor

The Porsche oxygen sensor monitors exhaust emissions so that it can accurately analyze air fuel ratio going through the engine. The concept here is somewhat complex. In a nutshell though, your Porsche needs enough fuel supply to ensure the fuel burns properly in all combustion cylinders. Once this happens, the engine runs smoothly and the car accelerates without any problems. The sensor sends data to the computerized engine unit on the amount of fuel the car uses.  If the sensor gets damaged or malfunctions, the car will have no idea on the ratio of air to fuel it should use. This will cause a lag in acceleration. You can have the sensor fixed or replaced depending on how badly it is damaged.

A Faulty Throttle Position Sensor

Your Porsche’s TPS detects the throttle valve opening angle as the engine runs. The angle is always controlled by the acceleration pedal. TPS transmits this data to the ECU. This means that if the TPS has a problem, the engine speed cannot in any way be controlled by the accelerator pedal. The engine speed will in turn decrease or increase without any depress or press on the pedal.

Clogged Fuel Filters

Fortunately, this is a problem that shouldn’t worry you. That’s because with time, fuel filters clog.  There is no way you can prevent the clogging. Your best bet is to take your car for regular servicing to ensure the fuel filters are always clean. With a clogged fuel filter, the engine will not get enough fuel so it goes without saying that acceleration will be slow. In cases where the air filter is completed clogged and dirty, the car will have a hard time starting. Simply replace the fuel filter.
