It's a 1996 6.5L K3500 with 4x4. 4" exhaust
Description: Only the first start of the day, when temps have been 50-60 or less overnight, I have a sluggish cold start condition. The RPMS fluctuate between 400-100 it sounds like, and the engine is barely running and shaking for 5 seconds to over a...
DS-4 Fuel had seemed to be increasing over about a month now evidenced by increase of black smoke. Now I have a massive amount of bellowing black smoke and miss in the 6.5td.
No codes, starts easy, shakes and puts down a black smoke screen.....does not stall.
It boosts ok.
HELP!
