I would suggest focusing first on a vacuum leak. However, you need to do this testing when the engine has the high RPM. Once the RPM drops the leak is most likely gone.

The other possible cause the the PCM thinks there is more air coming in which would be a MAF/MAP sensor issue. So let's check for codes as well

We don't have a manual on this vehicle as it is not offered here in the USA but I think we can still uncover the issue with running through this material.

Let us know what questions you have. Thanks
