Hi, regarding your post about cayennes rough idle and hesitation at 3000 rpm . what was it ? and did you solve it ?
I have the same problem as you... everything fine while driving . When starting the car in the morning everything fine for as long it warms up and turns around 1000+ rpm , but few minutes later when it reaches normal idle (580 rpm) it*s staring to be rough and pulsing vibration. . no error codes, no misfiring nothing . also with new spark plugs.
warm engine : when i reach 2600-2800 rpm in parking mode , i notice a small rough eruption every time , which is very short and light , but nothing rough in the range before or after...only close to 3000 rpm.
hope you can help me !
thanks in advance !
