My '01 S40 T1.9 (78K miles) has an annoying miss (it's actually more like a
brief stumble) at idle - it'll idle smoothly after coming to a stop then
after about 10 seconds, the engine will start missing. The miss interval is
variable - sometimes 3 or 4 in quick succession and other times more spread
out. Most of my driving is around town but when I take for an run on the
interstate, the missing subsides for a short time. At speed there is no
roughness or missing, just at idle.
Any ideas where to start looking would be greatly appreciated.
