Spotting abnormal engine behaviour on his car is not a good sign. Indeed, the engine is the main organ of your car and any sign of a malfunction must be spotted directly and you must look for the cause of this malfunction. If you are ever in the situation where your car no longer accelerates, whether uphill or downhill, we have compiled this file to help you understand the source of your malfunction. To do this, we will review in turn the majority of the reasons that may justify your car not accelerating smoothly.
My car no longer accelerates properly because of ignition:
Let’s begin our recap of the causes that can cause your car to stop accelerating properly. One of the most common causes is that your ignition fails. We talk about ignition, but we can also generalize the malfunction to the ECU which itself can transmit bad information that will disturb your ignition. It can happen that your car has been put in safety, do not hesitate to read this file for more details. To check that one of these problems is not the reason why your car no longer accelerates, you will need to run your car through the diagnostic tool. Moreover, you can check the state of your ignition coils, if you have several of them and one is faulty it can explain the acceleration holes you feel, if you only have one in normal circumstances your Peugeot 208 should not start.
My car no longer accelerates smoothly because of the injectors:
Let’s concentrate on the problems with the injectors in your car. If you have the feeling that your vehicle is grazing, that it suffers a loss of power, it is quite possible that because of a bad fuel quality one or more of your injectors have obstructed or clogged, which results in a bad air/fuel mixture sent to the engine and which will therefore automatically disrupt its normal operation, do not forget to check the state of your injectors. If during the check you find that one of your injectors is leaking on your car, do not hesitate to consult our small file to remedy this malfunction.
My car no longer accelerate as before because of the accelerator cable:
Another possible justification for the fact that your vehicle no longer accelerates, whether you are driving, stationary, hot, cold or accelerating, is a pronounced wear of your accelerator cable. If the accelerator cable is at a pronounced stage of wear and tear, it will not slide properly in its sheath and will produce a loss of power, check the level of wear.
My car no longer accelerate because of the clutch:
One of the classic causes of a car not accelerating when hitting the gas pedal, or not moving forward, is that your clutch disc is dead. In fact, the function of the clutch is to transmit the power from the engine to the gearbox which will then transmit it to the wheels. If this disc is “smooth”, you will no longer be able to transmit this power to the wheels and you will find that your car no longer accelerates, or at least, the engine may rev up, but the speed of your vehicle will have difficulty increasing. Browse through our file on the clutch that slips on your vehicle, to test yours and check that it is not the cause of your malfunction.
I do feel a loss of power when I accelerate because of the fuel filter:
As far as the fuel filter is concerned, we are dealing with the same type of problem as blocked injectors. If your car no longer accelerates and you have the impression that it is grazing or that you have holes when accelerating, it is possible that your fuel filter is clogged. The consequence would be that your entire intake system is idling and therefore your engine lacks the fuel supply to operate normally. Don’t hesitate to check it and replace it if necessary. In case you have the impression that your vehicle rises in laps by itself, read through this file it should help you to locate the cause.
My car does not accelerate any more because of the particulates filter:
The penultimate explanation for a car not accelerating, comes from your exhaust system. Today’s vehicles are equipped with more and more options to limit pollution emissions, the particulate filter is part of this package. However, depending on your use, it is possible that it can become clogged and blocked. Especially if you make short journeys and can mount your car in the towers. In this case it is possible that your particle filter gets clogged and that your car does not accelerate anymore. Get it checked out.
My car does no longer accelerate because of a punctured hose:
To conclude, last explanation, and certainly the least annoying for you, it is possible that one of your fuel or air intake hoses is punctured or cracked and that it causes a lack of air or fuel which will result in a car which does not accelerate any more, check under your bonnet, engine running, the level of wear of your hoses, be careful not to burn yourself. If ever you are in this situation, it is possible that your car does not hold idle, in this case consult our small file to treat in depth the dysfunction.
