Technical Running lumpy

[Diggerg]

Hi all. I have a 14 plate 1.3 multijet doblo cargo. Just had 3&4 injector seals done as they were leaking.
When I removed the air box to find which were leaking I noticed the crankcase breather pipe and the short one that continues it to the turbo intake were full of oily sludge.
I cleaned them as best I could but now it runs lumpy until about 2000rpm.
Any ideas?

Only thing I can think is dodgy map and maf sensors so got them on order. Also ordered OBD2 plugin to link multiecuscan

@varesecrazy for the ECU to learn the new sensors is it just a case of disconnect battery while I swap them out, and wait the obligatory 15 mins or is there more to it?

I believe they are not too fussy..and that will wipe the learnt memory..

They will adapt as you drive

My bunged up MAP sensor.

@varesecrazy , so I changed the maf and map and no improvement. I think my injector is knackered. Is there a way to check the voltage at the injector to rule out bad wiring?

Ok so no real change with the new sensors in place. Lads at work plugged their snap on code reader in and cylinders 1,2,4 have a fuel trim of -2.5 ish while cyl 3 is +5.1. I've ordered a new injector and hopefully get to the bottom of it.

So new injector fitted this morning and running sweet as a nut.
