Hello,
I have recently aquired a '90 BMW 318i, it has run 230k km and is in pretty decent condition.
However, when at constant throttle - regardless of which gear - I am experiencing a surging / cycling of the throttle. As a result the car goes faster and faster. Well, not _so_ fast. ;-)
The sympthoms are as if I were slowly pressing the throttle down and releasing it, ending up at a higher throttle setting than previously and repeating it.
I have recently swapped the fuelpump as it died, but the problem was there before that.
Any ideas?
