So Tom and I were working on the Rally car this weekend (which involved tom fixing things and me injuring myself with power tools .. angle grinders can really hurt

)
We discovered my O2 sensor is broken, like way broken , little porcelain pieces falling out and what not. I disconnected the O2 wire Sunday on my way to napa and no sputtering.

put in the new O2 sensor and so far so good. I won't really consider it fixed until i've driven the car about 5 days. (the problem was intermittent )
could this explain the gas smell i was getting on occasion. (makes some sense right?)
as all of the spark plugs indicated the motor was running rich.
car seems to be running a bit better (need less throttle to climb hills than before) won't really know until i can check gas mileage again, i was getting 30 (29.5) right after the motor swap
