Hi all,
Looking for some help with my 1998 E36 touring 318i (M43).
When cold and warm there is a clear flat spot between 2000-2500, and further flat spots through the rev range further on, and seems to be getting noticeably worse.
Also noticed when the flat spots occur, the fuel economy needle fluctuates quite obviously.
No warning lights or error codes flagged.
Any ideas of possible cause or tests to help diagnose?
Thanks
Rob
