Finally had a day off from work so I checked the tps voltage at the cars ecu and it appears to be accurate. Idle was still really rough. I tossed the old spectre filter and picked up a new k&n along with some more maf/electronics cleaner and tb cleaner. I completely removed the CPe intake and cleaned the throttle valve. I took another look at the maf and found it a little hazy so I sprayed it again a couple times and this time and went over it lightly with a tooth brush. I reinstalled the intake, new filter, hoses and maf. I unhooked the battery for a half hour and then reconnected it.
I started the car and it idled quite well. I let the car idle for a half hour to relearn the clean set up and then took it for a pretty long drive. To my surprise the idle is once again perfect.

Thanks AC for the help. Your post made me go back and recheck the maf which I'm thinking I didn't clean well enough the first time through.
