my car has no power at all after about 4500 rpm. It feels as if the ignition signal is breaking up or somthing.

Any idea what this could be ?

The only thing i can think about due to the low amount of description is perhaps your fuel injectors, stock ka? …?

Welsome to the KA powerband. All low end torque and power. Go turbo if you want higher bandwidth power.
