dle Issue Update:
Today's course of action went something like this..
-Removed IAC Valve, cleaned and re-installed replacing the gasket.
-Cleaned around throttle plate inside the throttle body clearing away gunk.
-Started and ran engine, problem persisted.
-Picked up a new MAF. Installed. No change.
-Acquired new IAC Valve. Installed. Ran Engine, problem worsened. Engine idle dropped really low to where engine made a chattering noise, shook, then died. Third start, after an intimate moment with my creator was had, engine started smoothly and idled. Less lunging when putting through parking lots and much smoother all around throttle response! Thanks for the helpful links and hints everyone that helped.
