Marshall,
Can a bad injector also cause extremely low idle speed (500 rpm) and
stalling at startup? With a warm engine idle is a normal 650 rpm (1983
300TD)
Well, if each injector/cylinder supply 1/5th of the power to turn the
engine, you might expect the speed to drop by 20% or a bit more if one
didn't inject ANYTHING or didn't inject what it was supposed to, when it
was supposed to, as it was supposed to. Proper idle speed when warm
should be 750 rpm - NOT 650! It WILL be a little slower when cold!
Many older engines need to be set to 800+ rpm to prevent stalling when
cold. I don't know how much of the problem relates to the condition of
the injectors, to the condition of the injection pump or the condition
of the timing chain (and thus pump AND valve timing).
