1998 V70 Fault light on and cuts out at idle

[jgasn]

Hi, had a problem today with the car cutting out when coming to a stop.
98 V70 5sp non turbo with 165k.
O2 sensor replaced at 80k/8 years ago. Will idle and rev no problem when cold. K light symbol on dash stays on the whole time. Cutting out happens when the car is up to temp and a short time after i have come to a rolling stop. Have not had a chance yet to get to shop to read codes.
Know it sounds a bit open ended, but thought it may be a common fault or if there is a simple test i can do to sort something out.
Did a stage 0-1 at 100k.
Ever since I have owned the car (8 yrs), there has been a intermittent drop in revs at idle, may happen couple of times a week or once a month. This is the first it has cut out completely at low revs.
My regular indie is booked out till the end of the month. Thanks.

First step, read the codes and report back. Check the idle air control valve and hoses for tears, rips, holes, animals..

I wonder if the cutting out is the fuel pump relay. Test by jumpering it.

The intermittent idle drop is common when there is an aftermarket or failing MAF, or when the TPS is bad.
