Ive had my check engine light on for a while now. So I took it to the local tuner shop 6 months and 1200 miles ago to have a exhaust system sized up for my 98 CG3(ACCORD EX/4). The guy noticed the light after doing my regular scheduled maintanance before tuning the car. He pulled the code and knew right off hand it was the O2 sensor. It read BANK 1 O2 on his diagnostics. Well 150 bucks extra later from HONDA the problem resolved. No more power loss and that gasoline smell when I parked the car is no longer there. Oh..Its nothing special AEM CAI HID Conversion DC SPORTS HEADER 4-1 RSX Custom fitted Muff and pipe O.E. MID PIPE/Cuz the suckers got 3 O2 sensors and Im tired of fooling with it. Any Who the car runs a whole lot better. HONDARACER2K
