Why is my renault megane losing power?
2-Renault Megane 3 power loss: Injector problem So it is not giving your engine enough fuel, which can be the reason for a loss of power. In order to preserve your injection system we recommend that you check your diesel filter from time to time.
What makes a car lose power?
There are many reasons why your vehicle may be losing power, especially when accelerating. Some of these common causes are: Mechanical problems such as: Low compression, clogged fuel filter, dirty air filter, clogged Exhaust Manifold. Malfunction of actuators such as: Bad injectors, bad fuel pump, bad spark plugs.

What happens when the glow plugs fail on a diesel engine?
Hard starting. Unlike gasoline engines, which use a spark to ignite the fuel mixture, diesel engines rely solely on cylinder pressures to ignite the diesel fuel mixture. If the glow plugs fail, the engine will have to overcome additional pressure in order to ignite the mixture, which may result in hard starting.
What causes a car to lose power when accelerating?
If these impurities were to get into the engine, they could cause severe damage. However, air filters tend to get clogged after they’ve been used for a while. Once an air filter gets clogged, it will limit the amount of air that can get into the internal combustion chamber.
What happens when the spark plugs fail in a car?
After the ignition coil sends an electrical signal to the spark plugs, they transmit that signal to the combustion chamber so that its air & fuel mixture can be ignited by an electric spark. If the spark plugs were to ever fail, then the engine’s performance would diminish and eventually fail altogether.
