Hahahhaa. Been there done that!
Here is the list:
check the psi on the fuel pressure regulator. If it is at all high replace
it.  That was the cause of my headache for a few months...

Temp2.  How old is yours? Check the resistance per bentley. Even thouhg it
may read in the ballpark or dead on, it may be bad. There are a few cases
of this on the list where things like the connector was bad.

Oxygen sensor. Get out the book and check it too. Again how old is she? If
she is old that could be bad.

fuel injector- make sure they are not stuck open per bentley. Check the
spray pattern.

Beware that running rich for a long time will cause your catalytic
converter to clog and stop working.
