1991 LS400 sudden power loss

My 1991 LS400 has had a sudden loss of power, it ran perfectly when i parked it the night before. it does not miss or backfire but it smells to be running rich I'm wondering if it has a fuel air mixing valve that could have failed. The problem did not occure while driving it started as soon as I started the car in the morning. ANY SUGGESTIONS.....

That means it has a miss. Either you need new spark plugs, wires, or a bad coil. Make sure all the spark plug wires are on all the way.
