I have a 2008 Porsche Cayenne GTS, I had the oil changed yesterday and now today my car runs fine but when I hit the gas pedal it wont go over 2 RPM and makes a high pitch winding sound! Any advivce??

Have you checked to see if it actually has oil in the engine?

As I said before, It just got the oil changed. So YES it does have oil.

But did you check the oil level yourself? Sometimes the kids at the rapid lube places get in a hurry and forget important things such as oil.

it was changed at the dealership not at a rapid lube
