FIAV or ISC is a good bet then.

also, I have a one inch hole in my flex pipe. It isnt just a normal hole, it goes all of the way around the flex peice. Could this cause bad idle and occassional misfires? I was told yes.. and no. So ima bit lost. I Am getting a new downpipe tomorrow morning and i guess i will see then but im a bit anxious to find out cuz yea. Any info would be awesome. Thanks
