Cummins 8.3 ISC Black Smoke @ cold Start
Hello everyone,
I have a question about our Bluebird 8.3 ISC. if the bus stands still for a day, it throws out a black cloud when it starts. everything is ok during the journey. only if he has been standing for a longer time at the start. is that normal so far? it does not have a particle filter.
Best regards
