    Erratic idle/revs

    I first thought this was to do with the Brake master cylinder leaking into the servo...This has all been fixed now with another Mater cylinder.

    When starting from cold or driving and coming to a halt the engine revs drop right down as if its going to stall. I HAVE ALSO NOTICED THAT IF I PULL AWAY QUICK FROM STANDSTILL THERE IS A MASIVE HESITATION/DELAY BEFORE THE ENGINE PICKS UP AND FLY'S AS NORMAL.
    I WOULD PRESUME THAT THIS IS SOMETHING DIFFERENT FROM THE BRAKE FLUID LEAK WHEN ALL THIS CAME TO LIGHT.?????

    Any ideas please.???

    Thanks

    mine does the same but only an intermittent fault at the moment. sometimes it'll be fine for 2 weeks then it will have a bad patch for a couple of days and then be ok again! Mine's an S70R though. I've changed my plugs, and my leads are next. If it was the air flow meter I'd have thought it would do it all the time, but a breakdown in one of the leads would account for it.


    Bailey dump valve + Boost gauge + Manual boost controller + K&N induction kit + Powerflow cat back exhaust + Strut Brace + Bilstein shock n sports springs with 40mm drop
    = very fast and still turns corners
