Escort diesel. Tickover lumpy & smoking?

Have a '96 1.8 Escort turbo diesel hatch.

140K miles but in decent nick. ish. Oil & filter regularly changed at 5k, all other filters changed at 10k. Cam belt & tensioner changed every 30k. Valeted regularly, normally the day before mot. Recently, and suddenly, it has become very lumpy and smokes excessively at tickover/idle. No apparent smoke above tickover and performs well. Any ideas please why it is lumpy & smokey at idle speed. I don't have any diagnostic kit and the old car isn't worth spending a lot on, but it is a good everyday hack for supermarkets, garden centres, vets etc.

Thanks

Nick.

try shutting it down, cycling the glowplugs and starting again.

My 99 Escort Diesel is the same - dud(ish) glowplug on 3 does the same which makes for lumpyness after filling up, for example.

Ah, sorry. I don't mean just from cold. Even after a good run of 50-60 miles today it is lumpy and smokey when, say, waiting at traffic lights. Handbrake on and increasing revs stops both but does not cure the problem. Had a problem with a glowplug a couple of years back and replaced all then. Even of the coldest morning it starts V well.

Cold start timing advance on the injection pump is stuck on.
