Hi all
I would appreciate a bit of advice about my car, it is a 2001 525i (M54). It runs fine and idles perfectly most of the time but sometimes without warning, it is difficult to pull away from rest smoothly, I noticed when this happens that the idle speed goes up and down by itself, from a few revs up to about 1000rpm and when doing this sometimes stalls altogether.
A couple of times it seems to lose all throttle response when driving, don't know if this is a different problem.
I have checked the codes etc with inpa and it says that there are no errors, I have removed and cleaned the idle control valve as per suggestions on this forum (it was stuck). I have also checked for vacuum leaks, the small blanking plug at back of engine was split so I replaced it, I couldn't find any other leaks.
Any advice would be very much appreciated,
Cheers
Paul
