I've only had my 92 LS400 for a few weeks but one thing I have noticed is that at idle it smells a bit rich? Is this a typical LS problem?

Before I got the car the plugs, wires, rotor buttons, and fuel pump had all been replaced. Also some seafoam was run through the intake. If i'm sitting at idle with the windows down I can smell a bit of unburnt fuel. I have not noticed any gas leaks anywhere. Gas mileage seems somewhat normal (got 21.6mpg last tank, 80% freeway).

Any ideas?

Ignition coils. Try them first.

Gas mileage sounds low unless you are going 80

but like Avalon said, check the ign coils.

I thought the ignition coils were generally only a catastrophic failure with one bank completely going out? What should I be looking for when checking them? Car drives completely fine with no sputtering, missing, or lack of power.

Replaced both ignition coils yesterday, runs exactly the same.
