Been there with our old Chevy Venture van.  Obviously a completely 
different layout than your S10, but in the end I took off the front upper 
motor mount and tilted the engine forward, plus found a combination of 
tools to get to the o2 sensor.

Which might actually help... The parts stores around me had a couple 
completely different o2 sensor removal tools.  That let me try different 
approaches.
