Wondering if anyone else has experienced this. It's happening on my '02 V70XC.
Car starts without fail when cold but recently. I've had a few instances (maybe 8x over the course of a couple of weeks) where I get back in car after having done whatever (say grocery pick-up) I start up the car, revs up to maybe 1200 rpm (whatever is normal when engine is warm) and then drop down to 700 where it very briefly holds and then dies altogether. 75% of time, when I try and restart the same thing happens.
