alright guys here my lil situation ... i dont think its bad but i thought i would get a 2nd opinion from you guys !! i was throwing a IACV cel on my 2000 civic si which i hear it happens alot and the idle was really messed up and every now and then at light the rpms would sit at about 2000rpms and fluctuate up and down about 300 rpms really roughly and when i would drive it would be REALLY rough no matter what gear i was in or how lightly i touched the gas ... so i posted up here and alot of people told me to clean it or replace it ... i cleaned it and after a few weeks it came back soo today i met up with a friend that had an extra one off his old 96 civc ex and when i was comparing them i noticed the whole on the left was a lil smaller on his then it was on mine but only by 1mm or so and i went ahead and put it on and it seems to idle fine ... so my question is , is that bad or will i loose performance or is it ok !?!? thanx guys

Does it work correctly? It will be okay. I think it just lets air in at idle anyways.

yea i just took it to get gas and it works fine ... my idle is at about 850-900rpms and everything works good ... i just wasnt sure cuz the whole was a little bit smaller
