I just drove my 87' Syncro from Wisconsin to LA California, My vans engine
will run perfect and smooth, until 60 sec. or so later it loses power,
black smoke comes from the tail pipe and it sounds like it's missing bad.
Things tested and replaced: Head (burned valve), both coolant sensors,
"Flapper box", plugs, wires, cap, rotor, ground connections,O2 sensor, Cat.
Timing and CO where set by a local shop in Illinois. Heres thr kicker, if I
quickly turn the ignition switch off then on while this is happening,
everything goes back to normal for 60 sec. or so then it does it again,
flip the switch etc....HELP!
