It's running VERY rich. Change the fuel filter; check fuel pressure with a gauge; pull the Red vacuum line off the FPR while the engine is idling & check for the presence or odor of gas; check plug color & gap; check plug wires & routing; check catalysts for damage; keep the engine running continuously for at least 30 min before testing.
