So we know that these cars run rich from the factory, which is probably why the O2s, pre-cats, and main cat go bad prematurely.

When my pre-cat died, I decided to just install MIL eliminators. I passed emissions inspection shortly afterward.

I'm due again for emissions testing, and I'm worried because of the strong smell of gasoline, especially when I start the car. I can smell it from the driver's seat coming from the tail pipe, which is looking sooty. I've been getting 24 mpg with 50% city driving and 50% highway.

Any suggestions for leaning out the air/fuel mixture? I haven't had a CEL since installing the MIL eliminators last Spring. I now have 83K on the car.

EDIT: Would getting more air through the intake help the mixture or would the computer simply add even more fuel? If there isn't a mechanical way to fix this, then I suppose I will have to get a programmable MAF or SAFC.
