[MR2] MK I engine check light

[Chris S]

ya know...that was going to be my 2nd guess..I forgot what killed my O2 
sensor, but i remember having a strange "check engine light' while driving 
at highway speeds with no apparent problem...

the other funny thing was that my gas mileage didn't change when my o2 
sensor was dead,b ut it was aaabsolutely dead...

easy check
