You are talking about the wrong thing my friend. We aren't talking about an Air inlet Silencer. We are talking about the little black box connected inline with the IAC (Idle Air Controller)

The line runs from the intake tube, through the silencer and into the IAC. If you plug the line in the intake, then you've still got the IAC sucking air from open atmosphere. Probably make for a really dirty idle.

OK...Sorry guys, I was talking about the wrong thing.. your talking about the black box in the middle of the pic over the intake manifold. My car is 32V so it looks way different & it doesnt have that box...

So that box keeps the IAC noise down huh? Well, my truck (ranger) makes an ungodly humming sound ... I wonder if I put the box off my car onto my truck if it would help? What yall think (besides get a new IAC)

as long as the line goes from the intake tube to the iac(so the maf see's the bypass air)why can't you remove the silencer with no ill effects?

Edit: I tried removing the hose at the IAC and the car wouldnt stay running (just to see how it sounded .)

Yea if you remove it while its running it will die....other option is to pull it off and put your hand partly over it to keep it running, OR crank the car up with it off.

What they did was place their hand over it to keep it from ding and slowly started allowing more air in and it quickly learned and idled by itself. It was darn cool and did the ROMP, ROMP, ROMP thing at idle for a while and then started "hitting" Sounded

Who said you couldn't? The silencer is there just for noise control, nothing more. That being said, there really isn't any reason at all for removing it either. There are no ill effects or advantages for having it on, or bypassing in either case.

Wait Cody, so does that mean if i unplugged my iac while the car was running and it didnt die its time for a new IAC? My car has an idle that drops to like 400-500rpm's when coming to a stop and then hangs at 1100 rpms at times. Would that be my problem?
