stumbling down the interstate



DK if it's your solution, but my experience with stumbles/cut-outs ended
when I installed a new idle control valve. Part ran $109 and was easy to
replace myself. That was at about 122,000.

Subject: <E28> more stumbling problems
 
With the recent posts of 535i running problems, let me toss mine 
out for review and discussion.
 
Traveling the interstate - cruise control on - anywhere between 70 
and 80 MPH - 5th gear - the engine will start stumbling.  It will lose 
power - stumble - pick up - stumble - lose power - and the "battle" 
is on!
 
Well..., if I downshift to 4th - increased engine RPM - the stumbling 
stops.  Same thing for downshifting to 3rd.
 
Go back to 5th - "resume" on the cruise control - and in a short 
period of time - stumbling and all begins again.
 
Sometimes it will go away - and not return - for a few hours - or a 
few trips.
 
Have checked the gasoline - nothing there.
 
Working with my local technician - we are baffled.
 
What say you?
 
Thank you for reading!
