i didn't think about that. thanks!

i figured it out. it's the mass air. this morning i took the intake apart and inspected everything. no cracks or loose connections or anything. so i put it back together and started it up. still the same thing. but i had the idea to just disconnect the mass air while it was running. perfect engine. perfect idle, revs, steady rpm about 4000. everything. so it's definitly that.

my only question with that is what the hell is my mass air for?

If everything that you can see/get to seems to be in good shape... it's probably a gasket somewhere inside the engine. Mine did the same thing and was a crank case gasket... replaced and the whole problem immediately went away.
