hi I've got a problem thats really annoying me when i put my clutch in as I'm slowing down to park up outside my home the revs drop down to zero as if its going to stall then shoot back up its been doing it for a while and is getting slightly worse any idea's on what it could be ? thanks
 
Same for me, havent been able to fix it yet. New MAF fixed it for half a day, then it was back...
 
Something To Do With Fueling Maybe ? Or Pcv ? Have you scanned it for any fault codes?
 
just put a new DV on the car so its not that, unplugged the maff sensor today and it stopped doing it so think i might have to get a new maff sensor and try that
 
Throttle body clean? Have you checked fuel trims on vcds? Any boost or vacuum leaks?
 
cleaned the throttle body out last year don't think theres any boost or vacuum leaks as it still pulls very well will check the pcv valve at the weekend , as to the fuel trims you mentioned I've no idea on that
 
What about clutch switch? Fault code scan would be good.
