Yet Another Rough Idle

Well cleaned the throttle body today with Valvoline's Carb/TB cleaner and no luck. Still have the strange lope present.
Getting worried it might be the IAVC, at least I think that's what its called. Anyone know of a good way of checking this before I drop 400 on a new one?
I also noticed when my idle drops about 100-200 its typically when my engine fan kicks on... Not sure that means anything, just an observation.

Well time for another update...
Car threw a CEL...
P0453, P0450, P0300
Im guessing whatever is causing the P0300 is my idle problem but not sure where the P0453 and P0450 came from, although they both point to the evap pressure sensor.
Im going to search the forums to see if anyone else has had this same combo of CELs.

Could the lean be caused by the gas leak by chance?
Awhile back, about a year ago, I was rear ended and had to get the entire rear end re-built. I believe I had a check engine light at that time as well that was related to the Evap Canister (Code P0455). The canister got replaced and my rear repaired with no issues in the past year.
All these headaches I'm having now started shortly after I completed my TBE install.

After checking the Service Manual Ill probably try to veify the cause of P0453 and P0450 by first checking the voltage level across the fuel tank pressure sensor.
I'll post what I find...

Still trying to track down the cause with no solution. I have a Noon appointment with the local tuner here Saturday in hopes he might be able to help out.
I'll post any results we find... Hoping we can solve it and I can get tuned finally
