Without knowing the engine size. I will Guess: find a picture of the part first, then locate it on the INTAKE MANIFOLD. there are 3 valves there , so get a picture of the right one first.

SOURCE: 02 monte carlo, radom misfires, EGR circuit failure

Does it misfire under load like when you press on the gas peddle after slowing down then accelerate or at idle. When you say spark plug did you mean all the spark plugs?

SOURCE: power loss

Can't answer your last question but catalytic convertors that are just not working anymore won't cause any loss of power. However, if they have shattered inside (they are kind of a ceramic honeycomb) they can dump junk into the exhaust system that can eventually clog your muffler or resonator.
Checking whether this has happened isn't difficult; after the warm up of the engine, either you or a helper needs to listen to the exhaust note. If firing of the cylinders is still distinct, the system isn't clogged with shrapnel; if it seems to hiss at higher RPMs, it is likely clogged.
This effect is easy to miss; I've had two failures and when cold, the engine would pull fine because the chunks of ceramic would fall to the bottom of the muffler and glue together somewhat. Once hot and agitated, they would clog the muffler and cause a severe loss of power but the idle would be OK. A hill that I would normally pull at 70 MPH, I couldn't top at all; had to sit and wait for things to cool down before proceeding.
It also seems some engines appreciate a bit of back-pressure in the exhaust system because the car gained in mileage and pulling power for several thousand miles before the clog became critical causing the mileage to fall sharply along with the power.

SOURCE: EGR Valve replacement and Check engine light

Error code will have to be cleared. The way that cars know when to turn on the check engine light is that there is a recurring error for "x" miles or time, as long as that error exists in it's memory most cars will continue displaying the check engine light.
