86 syncro, I still have sputtering even after running dry gas, fresh gas and
installing a capacitor, aaaaaaaaahhhhhhh ! I'm out of ideas? I know this van
is capable of running fine.
    Symptoms I drive a few 100 feet down the road everything is fine and then
it starts losing power, regains it, loses it, back fires, a bit of black
smoke, I have to pull over, shut it off, starts fine and the cycle repeats itself.
Plugs, wires are fine

The light for the OXYGEN sensor had been on since day 1, but ran fine while
my friend owned it.

The water pump has a leak, the Clymer manual makes zero reference on how to
change it, man is it tight in there to get it out, I'mlooking for the best way
to drain fluid and get it out of there. TIA.
