Bad O2 sensor perhaps?

A leak in the fuel system, althogh this would tend to result in a bad smell.

is the o2 sensor comprable to the choke on a carburator, whereas when the
engine needs to lean & rich it makes the proper adjustment? Im thinking of
bypassing it with an appropiate electrical signal to the computer by way of a
toggle switch.
