Check engine light, running rough and more...

Car: Subaru, Legacy, 1998, 2.5l     -    Back to Fix-It    -    Subaru Legacy Repair Manuals

Q.98 Subaru Legacy Outback, 5 speed manual, 123,000 miles, just bought, no warranty car ran great and strong. Tonight after a 30 minute freeway run, sitting at a stop light, car began to run extremely rough, engine light came on and flashing. Huge plume of smoke trailed us as we drove the two blocks home. Fluids all check out, no apparent leakage on exhaust system. Let car sit for 20 minutes, tried to restart and would not, until I held the pedal to the floor as if it were flooded and it started, idled very roughly again. Gas tank on empty and it appears to be exhausting raw fuel. Any thoughts?

I already checked/done: Just research so far, looking a buying and OBD, any suggestions for that as well?

Answer the flashing check engine light indicates a misfire. That explains running rough.
what we need now is to narrow this down, need to know what codes are stored
i expect at least a P030? Code. Indicating what cylinder.
what color was the smoke ?
by the way if you can get to an autozone or kragen, i believe they still pull codes for free.
