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.

As mentioned check ps fluid. If it wines when turning and still no power then the pump is internally bad.. If the fluid is dissapearing fast then its a hose or most likely a leaking rack& pinion assembly..
