Porting the 02 housing worked for me. Porting the 02 and matching the exhaust got rid of it for me, and will be doing it to my new manifolds and 02 housings for the 13g upgrade i'll be doing soon. VFAQ has a nice bit about doing it, but i'm sure you can find someone on here to do it for you if you don't want to. If i'm not mistaken i think the 2g's have the same 02 housing as the 1g's, can get a ported and dumped o2 housing on e-bay fairly cheap.
