Yes (but then again, I was the one who told you to do that). Check the plugs too, they can tell you a lot by their condition.

Make sure your secondary air pump is not running all the time. it's the big ugly black thing on the L/H side of your car as you are looking at the engine.

Feel it to see if it's on. it should be off. if it's on, then that's why you have the lean faults. the misfire is something else I'm guessing.

Okay, slow down. What do you mean you changed plugs? (new ones, changed them around, what?) If you are adding variables then you aren't going to ever figure this out. In diagnostics you must change ONE thing at a time. If you change plugs AND move coils, you are doing it wrong. ONE thing at a time.

sucking air

had similar issue. it was the small vacuum line hooked up to the air pump...look at the vacuum lines that run along your head from the back to the front and attach at the pump...there should be some rigid plastic line and a short rubber tube attaching it to the air pump...look for cracks and worn vacuum lines. could be it.

What brand platinum 2's? Did they have the 4 pronged tip?

Not one to nit pick on small issues, but the problem you had no doubt stemmed from the 2 prong plugs. The OEM ones use 4, you need to stick with that. Probably the car had to learn how to run with a less efficient "burn" in the cylinders, I'd be putting the 4 pronged ones back in there if I were you.
