I would completely take the throttle body off the engine to clean it. The side facing the engine is going to be the dirtier of the 2.
Take the intake hose off, take the engine cover off. Unbolt 3 bolts and the connectors and the TB slides right off. 89 IN/lb when you put it back on.
Bank 1 o2 sensor is on the rear manifold. Not the easiest to get to, but not entirely hard either.

No, you don't need to drain the coolant. Only about 2-3 tsp should come out. As far as the gasket I'm pretty sure you could re-use it since it's rubber. But if you have a lot of miles it might be a good idea to replace it.

Yeah she's got 220,000 on her n I can see a lil bit of a gap as well so I mine as well since its gonna be off anyhow. That would be the upper intake manifold gasket if I'm correct right?

No, throttle body gasket. Huge difference between the two. The gap is not necessarily a bad thing. The gasket is pretty thick, if torqued down correctly there is a slight gap between the UIM and TB.

O my bad...hahaha I'm a bit tired. If that were leaking the tb gasket could that affect my fuel mileage?

It could but they rarely do. Your LIM(lower intake manifold) gasket is probably the first of gaskets to go on these cars. That leaking could definitely cause an MPG problem.

I wouldn't reuse the TB gasket. I thought mine looked fine, and then on the highway I heard a very distinct whistle, and had to buy a new gasket.
Better to just do it once, then have to take it apart again.
