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
Wendy
