Check for vacuum leaks. I would do a smoke test. It could be a number of things that could be the issue.
1. Do smoke test (this way you can check the whole system for a crack)
2. Check DISA
3. Check MAF
4. Check o2 sensors
5. Check Evaporative Emission Ventilation Solenoid
Many things can cause it and only you know the history of the car. If the hoses have never been replaced or the DISA then I would start there.

You do not have one in your vehicle. It's called a disa valve well at least the one I'm talking about.
