need help. running rough cold
I recently bought a 95 cummins. The first start every day it would run really rough,puff white smoke,and sometimes die when put in gear. Once it warmed up it was fine. I realized it was only idleing at 400rpm so i took it up to 800 and it ran perfect for 2 weeks. Now its back to the same thing even idleing at 800. I drained the water seperator and its still progressively getting worse. Could the lift pump slowly be going bad? Any ideas? thank you
