Intake mod question
 
Does anyone have that air box lookin thing on your intake? (Its like half way down the intake tube on the bottom and looks like another smaller air box). I removed mine when I did my TBS and it makes a ticking sound under the hood now. It sounds like air being sucked in thru the intake. I was thinking that the piece I removed kept the intake quiet and now that it was gone, you can hear air being sucked in at idle ( the ticking sound being the intermitent sucking action of each cylinder ). Either that or I'm worried the all the mods I have done are messing up the ECU settings at idle, causing the engine to tick. As far as I can tell tho its not a leak. Any thoughts?

On my 99' I have 2 air ducts to the left of my air box that go into the larger fender........Here a a thought for a free mod?.........I removed the larger one making the hole go from about 3" diagonal to a just about 6" diagonal. I then took a piece of the flat rubber insulation (goes around engine bay to seal engine bay and hood) from next to the air box and attached it to make a air scoop if you will. Kinda like this......(excuse the poor quality I used my phone)...
