First time poster on a car forum.
I have a 540i e34 which I love driving. Have been upgrading various components.
My 540i started running a bid odd with loss of power - seemed to start ok, but did not like a lot of throttle & eventually faded away to now not starting.
I tried "aerostart" & she fires up for short bursts.
This seems to be fuel related issue.?
Interested in thoughts from who ever cares to respond.
