Random Misfiring on cold

[Big_daddy]

My car misfires on random cold start engines,struggles start abit, sounds like running less 3 cylinders, rev it pops ands bang,
If i restart the engine it idles fine as it should on cold engine.....

i have same problem, was told it was wiring loom to injectors, then an injector, both been done at garage but no further forward, could try MAF censor

 

[sashaemmy]

is it petrol or diesel?

 

[Big_daddy]

hmm if wiring to injectors it be doing it all the time, with fault codes...
Maf new, new temp sensor...

 

[sashaemmy]

mine has come back, has no fault codes at all, mine was doing it only when warm to start with, then got worse until it was happening all the time, the new loom and injector has made a bit of a difference but still running poor, it feels like mixture is wrong so thats why i gonna try new MAF, did you say yours was diesel?
