[TOUGE-ITR]

Hi guys,

Long time reader, first time poster. lol.

I recently just got an EP3R and its got a catback and it seems to be doing the same thing that you guys have been describing.

its got a cat-back exhaust and injen CAI, i spoke to the previous owner and he told me
it only started happening after he did the catback and intake.

Im not sure but ive also got a faulty IACV i think, it idles at like 500 rpm which i know is way too low.

Not sure if this have anything to do with the problem.

Been readin the thread about how aftermarket headers fix the problem. I got j's racing headers installed on my ep3 and the sound it still there. I'm going 2 try the heat shield trick and see if that helps.
