86GT 5.0HO EFI, 5spd, PowerChip

Where is the O2 Sensor? I bought a Chiltons repair manual and it states that it's on the rear of the passenger side exhaust manifold(Header). I can't find it. Where is it on an HO?

The car has less than par throttle response, hesitates and surges upon accelerating and pings at low rpms. The pinging came about without changing timing.

The TPS voltage is at 1.05v, very recent complete tune up.

I don't have a Code Tester. Would I be wasting my time by changing the o2 sensor, could it be something else?

Please Help.
