    Start Stopping!!

    Hi Guys

    wonder if anyone has any quick thoughts on this one! Went to start the S2 this afternoon and as soon she fired up I noticed the engline was idling way too high at around 1500 revs which then crept up higher to around 2K. Might have actually gone higher but I killled the ignition and tried again. This time the engine turned over (a few times more than usual), fired up and then instantly died – revs never got above about 300. Kept doing this until I gave a little throttle as I turned the ignition on then it did fire up and run, but at lower revs at idle, around 600. Giving a little pep with the gas seemed to help and settle things to more or less normal idling.

    Went out for a short run (I was actually wanting to bed in the new rear discs and pads Ive just put on) – and all seemed normal. But it was just the same, starting up then dying instantly when I parked up and tried the ignition again. She will start, but only if I give a little throttle - so something aint right!!

    Need to get the codes pulled to get a proper idea but probably wont manage that for a few days, so any insight in the meantime welcomed!

    Cheers

      Dont know whats going on but I tried to start her again this morning and she fired up first time! Not that Im complaining in that respect, but its obviously something intermittent!

        Just a thought, had you touched ANYTHING in the engine bay before this started happening? Or did you move any wires or cables etc.

        Cheers,

          I would suspect a Sticky ISV - pop it out and give it a thorough blast/ clean with WD40

            Nope, nothing mate - I was working at the other end replacing the rear discs and pads. Only thing I did was unscrew the brake fluid reservoir cap to aid winding the pistons back in Havnt been anywhere near the engine bay otherwise all week.

            And, although I havnt driven the car today, I tried the ignition again tonight when I got in from work and she started first time! The car had stood for a couple of days when I first had the problem so that must have something to do with it. First chance I get I'll remove the ISV and give it a good clean One of those things I never got round to doing, tho I think it was a little simpler on the 7a!!

            thanks again guys!

              Could be lambda, if its not idling properly. Codes may show intermittent output.
