well bro, black smoke is too much fuel or not enough air, have you checked the intake for obstructions. For the miss, if you loosen the injector lines one by one while it is idling, you should hear the miss or problem go away when the nut is loosened. Not the injector itself but the injector line nut on top of the injector. Hope that helps.

This is kinda like a pressure washer.
3500 PSI pressure washer sounds like a lot.
But take that spray nozzle off so it is coming out of a 1/4" hole and it looks like water from a low pressure garden hose.
That said, when you loosen the injector line nuts, you should still use caution.
There is no guarantee that you will have a low pressure 3/16" stream of fuel around the nut.
Much better to error on the side of caution than a trip to the ER with fuel injected into you eye.
One of the fuel injection readings I watch on my Stroke is the mass fuel desired per stroke.
At idle the injectors are putting about 9 cc of fuel in each cylinder.
So that is probably close to what an IDI pump will be putting out on each injector line every time it injects fuel.
9 cc is only a couple good sized drops of fuel, not a stream by any method you use to look at it.

It still be pretty important to use a rap around the injector you'll be loosening, since hes doing this in a van, the engine is mostly inside the cab.
I'm sure he doesn't want fuel all over the carpet or dash.

9 cc = 0.01902038776979 pint
Sorry my converter does not do teaspoons.
Now you have me wondering if I have the metric units right.
A teaspoon per power stroke......600 RPM idle speed * 8 cylinders /2
2400 teaspoons per minute, that sounds high.
I have the units wrong, that works out to over 5 gallons a minute.

thanks for all of the tips,im going to try them today.and now the damn thing is leaking fuel from somewhere it is running all over the engine,i think it is coming from the pump on top.it leaks more fuel than it uses.it looks like the thing is on fire going down the road.
