Got a problem with my 940, it's a b230fk with a 16/19 turbo. Issue is when your slowing down the revs start dieing and it cuts out unless you build the revs up, seems to do it mainly when it gets up to temperature or after you give it abit of stick then slow down. I've tryed a different icv (used but was good on my last 940 and was ultrasonic cleaned) but that doesn't mean it's still good? Anyone got any ideas? I'm really fed up with this thing now, I've done a lot of work on this car and it all seems to be for nothing

Cheers guys
