Are you getting the popping coming off mid throttle (2500/3000rpm)to idle or WOT with higher RPMs to idle? Taking a few stabs at it Steve as cleaning the TB's shouldn't do this obviously:
-Looking at the parts diagram it appears you may have the emmision ports on the right side of the TB's that will have a vacum cap on each TB. I know on my 04, they were rotted and falling appart. Replaced and cured vacum leak reducing lean fuel mix.
-Check for vacum leaks at TB boots with some TB cleaner while running, small squirts and keep clear of paint. This is my guess where your prob is at.
-MAP sensor connection on the airbox good?
-Did you clean air filter and also what type of airfilter you got?
Hope this helps... Keep us posted.
