Hey guys... before I went hunting I thought I might try and trouble one of my more learned corvette owners...

I got an error code that turned on the Check Engine Light... hooked up my diablosport predator and it tells me that the left bank oxygen sensor is failing to communicate. I priced out the sensors for $88 each (might as well change out both while i'm at it I suppose) but I thought a little more carnal knowledge might help before I attempt to locate and change them out...

These are the upstream sensors (i disabled the downstream ones already)...

Are these accessed from the bottom of the car or are they in the exhaust manifolds? (Like I said... I haven't gone hunting yet) :) Any special tools, instructions or other procedure I should be aware of before I tackle this job?

Any help would be great!!

Much appreciated...
