Hi, Scotty!
I have a BMW Z4 E85, 2004, 2.5 liters, engine m54, automatic transmission ZF, mileage 104000.
I have the following symptoms.
The engine revs up and down for few times when I release the accelerator.
I don't have the same issue when idling.
Sometimes it takes longer than usual to start the engine if I do it within one or two hours the engine stop. But it always starts.
I don't recognize any problems with the automatic transmission shifting gears.
Is there a problem with the fuel pressure regulator or fuel filter?
Is there a problem with the automatic transmission?
Please help me understand the reasons and advise me on what needs to be inspected and how I can do it myself.
Thank you in advance!
P.S. Thank you for all work that you do all the time! That is so interesting and exciting! Where should I ask you to receive an answer in your youtube video?

Right here. There are no guarantees of course. Scotty can't broadcast them all.
