hey up all, got a bit of a puzzler for you. was on my way home in my mini tonight just crusing along at 65 - 70 and it started to loose a little power just intermitantly, then it got a little worse, and now its unbearable :S not only that, but its trying to come on boost sooner!!?? where it would sit on roughly 0 psi on the boost guage at 70 it now reads into the plus figures at 70 and 0 is right down at 45 - 50 it will still drive but on trying to hold constant throttle it coughs and splutters and generaly misbehaves :( was going soo well too!
ive had a quick look and i cant see any pipes broken off or anything obvious?
any thoughts would be most apreciated becasue im a bit stumped.

cheers
steve

Is it overfuelling? Check your fuel pressure as a start.
