First of, thanks so much for you help. It's really helping me narrow this down.
So I removed and cleaned DISA, it was ok, a lil bit of normal deposits on it, but it still had the rough idle once the engine got warmed up. Sprayed hoses around where you told me to do so and nothing.
At this point I"m assuming it can't be spark plugs or wires since when I turn the engine off, it starts up ok. It's after a little while of ideling that the rough shaking begins. Hope I'm right?
I also did what you said by removing the oil filler cap while it at a rough idle. Well, it had more of a vacuum suck to it once the idle was rough than it did when it was not rough. Not sure how much is normal?
What I did find out is that after a while, I left it in drive, removed the oil filler cap, and all of sudden my RPMs dropped, it started shaking even more to point where it wanted to stall. As soon as I put the cap back on, it was still a rough idle, but not as bad and my rpms went back up. Also, it idles even rougher in the following order from most to least: reverse - drive - park/neutral.
Any more ideas?? I would greatly appreciate them! Thanks again for your help!
