diesel injectors problem
hello
my problem is that when my engine is cold- the idle rough (gentle misfiring) and i get a heavy white smoke from the exhaust.
when the engine gets warm, and in driving- there is no smoke but the emissions is stinky.
{2 years ago i had white smoke problem - i replace 2 brand new injectors, and 4 refurbished}.
i have no fault codes present.
now i'm trying to understand the measurements of the star diagnostic for the injectors- maybe someone can help me figure which injector\s faulty...
this is the cold engine idle

this is the hot engine idle

this is the cold 1500rpm

You need to do a leak oil test to confirm which injector is faulty------Plus did you happen to open your eyes and read the lower left hand paragraph(see above F1) regarding variations.
