engine rpm surge. help needed.

[Rapom]

forgot to add... this may be key.. 2 other issus that could be related. both have been there since day 1. any electrical load... and even A/C does not affects engine idle. (it loweres actually) also putting into gear result in a 300rpm drop. 2nd clue is... i have ths weird loud clicking coming from the intake area under light load only. anything over 30% throlttle it goes away. is not there at idle. its not a valve or anything internal engine... sounds like a relay clicking...but loud. if i gas it up to 3-4k trans in park or N i can get it to do it aslong as im constantly increasing throttle (aka load)
