is your air filter clean?

I agree though...if your plugs and wires are new and in good shape then the O2 sensor should be next.

o2 sensor is right on top of the rear manifold.. right in the way of the rear spark plugs...

looks like a spark plug coming out of the exhaust

Soak that sucker for a couple days with penetrating oil (hot and cold at different times) before you take it out if it'* rusty. Then you can use a BIG crescent wrench.

Definitley soak it in penetrant. If it still won't budge, run the car 2 min then put a cold socket or wrench on it while the manifold is still hot. Be careful and wear gloves.
