When driving my car all of a sudden it would start loosing power and it felt like it was going to stop.To get going I had to pump the gas peddle but then it would happen again. A friend checked my exhaust and he thought that it was not the cause. As It is a Fuel Injector I bought a can of Wurth Fuel Injector cleaner and added this to my car when I topped it up with petrol but this has not helped.I am now desperate as I really depend on my car.
If you can help I would really appreciate it.

Many thanks

Could be caused by one of the following below

Throttle position sensor.

Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.

Note:If it doesn't apply disregard it and keep testing
