Terminal Updated on March 9, 2021
The symptoms of a car not accelerating like it used to can occur on many high mileage vehicles. A driver might non observe these signs in normal 24-hour interval to 24-hour interval driving only they go abundantly articulate when driving up a steep hill or when quickly trying to accelerate into fast moving traffic.
Need immediate assistance for your car trouble? Conversation online with an expert:
It is in those situations that drivers will come up to observe the obvious slow dispatch and the fact that the engine of their vehicle is struggling to go along upwards.

Common Causes of Car That Won't Properly Accelerate
This is a common problem in high mileage vehicles but there are no serious or immediate concerns regarding major engine problems. Some of the causes are actually minor and should exist checked first in lodge to locate the issue and possibly fix it also. Here are some of the most common causes:
#ane – Mass Air Flow Sensor Chock-full or Malfunctioned
The mass air menses sensor (or meter) is located and fastened to the inlet air cleaner. Since the function of the air flow sensor is to measure air mass that is flowing into air intake, a clogged or bad mass air flow sensor could send the wrong data to the engine ECU for calculating the air fuel mixture.
A very symptom of an air menstruation meter malfunction is car that won't accelerate correctly.
#2 – Oxygen Sensor Malfunction
An oxygen sensor is device whose office is to monitor the exhaust emissions of the vehicle so that information technology can analyze the air-fuel ratio going through the engine of that vehicle.
To make a long story short, a motorcar needs a proper corporeality of fuel in guild for the fuel to burn properly in the combustion cylinders so that it may run smoothly and may accelerate equally required.
This sensor sends the information about the amount of fuel being used to the computer unit of measurement of the engine and if this sensor become damaged, and so the engine of that vehicle volition have no idea what ratio of air-fuel mixture to use which may result in a fuel rich mixture.
This can cause the tiresome acceleration of the vehicle even with the accelerator pedal completely pressed making it unreliable when it'due south needed.
#iii – Malfunction of TPS
The basic principle of the throttle position sensor (TPS) is to detect the throttle valve opening angle which is controlled by accelerator pedal. Then the TPS will send this information to the ECU.
If the TPS malfunctions, the engine speed cannot be controlled past the accelerator pedal and engine speed will increment or subtract without any printing or depress the pedal.
#four – Dirty or Chock-full Fuel Filter
A muddy or clogged fuel filter is another reason for a automobile not accelerating similar it'due south supposed to when required to exercise so.
With a muddied fuel filter, the engine won't be getting enough fuel which means that the vehicle won't be giving the acceleration performance that it should. Supervene upon the fuel filter every bit soon as possible.
#5 – Clogged or Dingy Air Filters
Just like a fuel filter provides the engine with the clean fuel, an air filter provides the engine of a vehicle with make clean air to be used in the air-fuel mixture which volition exist sent to the combustion chambers to burn.
If an air filter is clogged, then the engine won't get the correct air-fuel mixture resulting in slow dispatch. Replace the air filter every bit soon as possible.
#6 – Timing Belt
This component is as it sounds. The timing belt is something like a VIP in the list fundamental of components of an engine. If this belt is off fifty-fifty past 1 tooth, it may cause some pretty notable acceleration bug.
However the listing of causes of poor acceleration does non terminate hither. Other culprits behind ho-hum acceleration may include a slipping clutch, the manual system itself, or an unexpected or unrelated problem which may surprise fifty-fifty veteran mechanics.
If y'all're not comfortable troubleshooting a motorcar that won't accelerate, I recommend taking the vehicle to a reliable mechanic and allow him requite information technology a total checkup. This will allow him to properly diagnose the result and recommend a suggested fix.
