I got a lovely "Check Engine" light over the weekend, but fortunately
found out it was only an oxygen sensor problem (and not a cracked
exhaust manifold).  Unfortunately, I also needed to get my front brakes
replaced, so I held off on replacing the O2 sensor to save some money.
Does anyone have a recommendation on where to pick up some new front
Oxygen sensors?  I'm on a college student budget and can get my buddy
to install them, but I was hoping to find a better deal than what my
mechanic quoted me.
