Cayenne 3.2 v6 no power between 2000 and 3000 rpm

Koen · 2019-03-02T12:15:00+0000

Hi everyone, I am completely new to this great forum and I am not natively speaking English so I hope I can make myself clear. My 2005 cayenne 3.2 v6 stick shift has the following problem. When regular driving it has very little power in the 2000 to 3000 rpm region. So I have to be very gentle with the gas pedal when I am between those rpm'. Just pushing the pedal slowly deeper by the millimetre. From the moment on the revs are above 3000 rpm the car runs fine. If I am a little more rough with the pedal the lack of power continues even above 3000 rpm. When in lack of power the engine makes a howling sound like when pulling a heavy trailer ... The only code I get is P0441. Can that code be related to this problem? (evap) And if so, which one of the related parts should be replaced? (canister, valve, solenoid ... ?) I hope you specialists can help me out. Thank you so much already! Koen (Belgium)
