Procedure: A more detailed step by step can be found here

remove intake box
remove throttle body
clean tbody
reinstall tbody/intake box
reset pcm

This is similar to the how to thread except I don't disconnect the battery to do the reset. I found a post here by mwfaith1971 which suggested removing the (2) pcm fuses (#10 and #28) for doing the pcm reset so I gave it a shot. It worked well. :cool:
