Start simple.

Sounds like it might be ok at idle to 1200 RPM or so. Change fuel filters. IF the tank is not real full, you might want to check the tank screen. Try that first, if it is ok at low rpm. How long since you tanked up?

On the way home today, about 3 miles from home, the '92 300D 2.5T lost power
and would only hold 60 mph in third gear, pedal to the floor, spewing grey
smoke. Came to a stop light, it idled smoothly and normally. Accelerating
when it turned green, the car had little power, started knocking, and
running rough at 1600rpm. I could get it up to about 2100-2200rpmmax. Let
off the fuel and let it shift to the next higher gear, and it would slowly
accelerate up again, same as before.

When I got home, I opened the hood, expecting to find the pressure line to
the ALDA, etc. off - but it all looks to be in place. With no load, rev'ing
the engine results in the shacking, missing, knocking, and lots of smoke
(grey) out the back. The smoke smells like raw Diesel.

Any ideas where to start trouble shooting?
