159 misfire like stutter on acceleration
My 1.9 jtd has developed a sporadic stuttering or hesitation when passing through 2.5 - 3k revs. Bizarrely, it only occurs under light acceleration (which is typically, most of the time for me) - if you give it more beans, it doesn't seem to happen.
On one occasion, after traversing busy traffic on a saturday afternoon, it got pretty bad as if one injector wasn't firing - a regular and very noticeable on/off power during acceleration through the same rev range. More commonly, it manifests as a hesitation and failure to pick up well - trying to write this I realise how hard it is to describe.
It's going into the dealers in the next couple of weeks as I have some warranty remaining so mostly curious at this stage - and really want reassurance it's not something potentially more serious that should be looked at now. I suppose my question is whether this is related to the EGR or something similar? I've been regularly using V-power diesel (about 1500 miles now) and have given it a proper hard run through the gears to try and clear things?
Aside from this, the car runs perfectly well... Anyone experienced similar and if so, what was the diagnosis?
