Fuel Filter Blockage: A blocked or clogged fuel filter can restrict fuel flow to the engine, causing the car to slow down and stalling in some instances.
Fuel Pump Failure: If the fuel pump is unable to provide sufficient fuel to the engine, it may cause the car to hesitate, stall, or run poorly especially when accelerating or going up an incline.
Fuel Injector Issues: Faulty fuel injectors may not be delivering the right amount of fuel to the engine, resulting in a loss of power and a decrease in fuel efficiency.
Ignition System Problems: Issues like faulty spark plugs, worn spark plug wires, or a malfunctioning ignition coil could lead to ignition misfires, rough running, and reduced power output.
Vacuum Leak: A vacuum leak can lead to a decrease in engine performance, hesitation, and decreased fuel economy.
Throttle Position Sensor (TPS) Malfunction: A faulty throttle position sensor can provide incorrect signals to the engine's computer, affecting the air-fuel mixture and resulting in engine stalling.
Catalytic Converter Blockage: A clogged catalytic converter can cause a restriction in the exhaust system, leading to decreased performance and reduced fuel efficiency.
