revs drop, when gas is tapped in neutral

[ianwells100]

ok, i have a 3" cat/catback, and CAI.

but, i've noticed that when in neutral (stopped), when i tap the gas, sometimes the revs kinda drop a little, go up, then fall down to 500 rpms, then back upt to hte normal 900 rpms at idle again...

is this a normal thing? i recently had my plugs/wires changed, have cleaned the air filter, new fuel filter, new pcv valve...

all i have left to do, is i guess check the o2's, clean the throttle body, and clean the IAC sensor..

any words of advice are greatly appreciated

Mine does this ever so slighty...but not to the extreme of 500 RPMS Mine only goes down to about 800-850 or so...and thats after the rev...it drops below normal, then rests at 900...

most of the time, it goes down an ounce, as you say, but when i tap it say 3 times in quick succession, it drops down a lot...

i wonder if its a sensor that needs to be cleaned/replaced, or something like that... if anyone knows, i'd greatly appreciate the help (although, really, its no biggie... i'm just anal about things that aren't 100% right in my eyes)
