hi all,

my wife's car has been super reliable up to now, touching on 120k miles now.

Lately it has develop an issue. First noticed when cruising at a steady speed on a dual carriageway maybe 60mph glowplug light came on then went out.

More recently, when engine is cold-ish at around 1500 rpm light load misfires for a second or so, then OK, then a few second slater comes back misfiring for a second or so, then OK for the rest of the day!

No issues when hot. As far as I can tell cold starts are fine too.

It has full main dealer service history, but the fuel filter has not been changed for a while, I think around 20-25k miles.

SO I will be changing the filter, but wondered if anyone has any suggestions? I am kind of hoping it's just the injector loom, as these are relatively inexpensive, but perhaps people have other ideas?

No smoke, blue white or black.

The car is a 2005 BTW. Many thanks!

MAF sensor?

Not sure, could be worth changing.

Yup, that's another possibility....
