alright so recently, about 3 weeks ago, i swapped a b20b into my teg. Car runs smooth in motion love the torque and what have you, but there is one slight problem. When idling, it idles a little hard, and "puts" every now and then. it doesnt try to die and like i said revs and runs fine when in motion, but this "putting" and harder idle is getting annoying. I have adjusted the idle screw and what have you many times to try and see if i can get a correct idle. it Idles at around 750/800 rpm. so its stationary from what i cantell i just dont get this "putting." I have many people told me that it is the IACV probably needing to be cleaned out.

I was concerned it may be the timing but it doesnt seem to mis fire or anythign of that nature and seems like it runs fine. I have searched this forum for something that looks to be happening to mine and i found a few threads but i wanted to make one of my own to explain my problem, i just want to get to the bottom of this. i am goign to clean it out this week and hope for the best.
