Question about Volvo S60
Had the same problem where the idle would go to about 500rpm and 'cough', i.e. move up and down and not be stable. Got so bad that when I was in traffic recently the car stalled every time I came to a stop. Turns out I have a bad oxygen sensor as well as MAP sensor. Expensive parts (about $200 each) though not hard to replace. May want to check those first. MAP sensor I believe controls something with gas combining with oxygen in the engine (too much gas, not enough oxygen to combust). I would press the gas peddle and not get much response. I was flooding the engine because that sensor was bad and that's why it was stalling. All stuff I learned after my very uncomfortable experience recently. I have a 2003 S60.
