Stuttering Astra 2.0 Turbo

When reaching 3500 rpm the engine starts to stutter in my Astra 2.0 Turbo and it will not rev any further. What could be the problem?

It may be prudent to have a diagnostic check carried out.

Other than that it may be one of the many sensors fitted to your car.
1. APP (accelerator pedal position) sensor
2. MAP (manifold absolute pressire) sensor
3. ECT (engine coolant temp) sensor
4. TC (turbocharger wastegate regulating valve) or the Intake divert valve
5. HOS2 (heated Oxygen )sensor
Hope this helps.

The heater fan on my Vauxhall Astra doesn't work. It used to work only in setting four, and then stopped working altogether. Replaced the resistor pack but it still isn't working.
