suspected worn injectors

[lel]

I think i have a worn injector on my 55 plate Fiesta Zetec S 1.6 TDCI!

The car drives as it should but the idle is lumpy from cold for the first 10 seconds or so and it chucks out a bit of white smoke on a morning. It has the infamous TDCI injector tap from around 1800RPM to 3000RPM when it suddenly stops.

I'm getting roughly 40mpg which is a bit low for these cars so i've heard.

I've done some research and i've had mixed results, some are saying worn injectors and others are saying they'll just need re-coding.

so if anyone with a bit experience with this problem could give me some advice i'd be more than thankful!

I had a similar issue on my old 58 zs tdci. I just buried my head in the sand and it still worked fine. Try some Wynn's injector cleaner first to see if it helps, my mates dad puts it in a couple times a year in his zs tdci and he says it reduces the lumpyness quite a bit. I think ultimately its new injector time though.

Worth checking it's not just the injector seals first a common issue & you can easily tell by looking for carbon build up around the injectors

i've checked the injector seals and they're all alright, they were all done 2k ago according to the history
