Hi, i have a 1987 MB 300d turbo six cylinder. I put new bosch injectors nozzles and calibrate each one to 2000 psi. The car after i started has a black smoke on iddle and a lot if i step on the fuel pedal. At the beginning the injector 1 was at 2100 psi and the injector 3 was at 1800 psi then i switched the nozzles and now all are at 2000 psi. I put an after market air filter and took out and installed the original, because it was smoking a lot more. With the after market air filter smoke like 60 percent more i do not know why. Today i was checking the vacuums i found one of the hose cracked and changed, but after that the car does not shut off, the one that i worked was the vacuum amplifier swithchover valve. I know that the the stop unit shut off the engine, but when i put the key the lever on the pump does not move. But now the most important to me is the black smoke, it is pure carbon coming out of the muffler. I put the engine on the 15 atdc and verified if the lug of the governor was in the center of the hole, all looks okay to me. I never work with a diesel engine before, but i like to learn reading the manuals and doing the work by myself, knowing the car i have in case of something happen on the road.
