ok, i know the sensor is on the exhaust manifold (drivers side) but is it accessible from the top? i see something that Im pretty sure is the sensor..but not quite sure if its it. (are there two sensors on l98's? i know my friends Neon ACR has one for upstream and downstream..) If anyone has a pic it would be worth a 1000 words... thanks

Should be just one....located on the pipe, not the manifold...I use about a 12 inch extension and a O2 socket, the ratchet then comes out about at the front of the valve cover (in reference) makes it real easy to get out and in.
