the smog saga continues... took it to get smogged. replaced the plugs yesterday. its really close to passing now. it's supposed to be 180 hydros or lower. mine floats around 200-250. im really hesitant to get a new cat on there because i feel like that's just throwing money down the drain. is there anything i can do. i disconnected the IAC a couple of days ago and it somehow brought the idle down. would this have anything to do with my problem?
