just an aditional note about O2 sensors - the 'narrow band' type found in most cars will either indicate lean, stoich or rich. The variation from 0.45V will not indicate how from off stoich the gasses are.
'Wideband' sensors will indicate the actual amount of O2 found in the gas - but these guys (until recently) are very expensive and require a lot more electronics to control and use (e.g. you cant just replace a narrow band unit with a wideband).
Also, until an engine is at operating temps and the O2 sensor likewise is at proper temps it will not read correctly and any decent ECu will ignore the O2 readings until then.
