Throttle hesitation

[shneidr]

Hey,

I have tried searching the forum to see if I can find something close to my issue but haven't been able to find anything. If I am repeating something that has already been covered please direct me to the thread.

I have an 03 E53 3.0. The issue I am having is after about 30 minutes or when its warm my vehicle will start to act as if I am pulling the max load on a trailer. I press on the gas and the response is very hesitant. If I end up having to come to a stop, it will idle below 500 rpm. It will also stall if I do not shut it off soon. It is time for its regular service but I don't know if that is the issue.

Also in the regular drive mode it seems that it will shift at a higher rpm then normal or hesitate shifting gears.

Thanx for the imput.
