i was driving home last night and the engine light popped on. i never did reset the battery after i got a new header/catalytic convertor/bolt on muffler so i reset it and the light when off. then driving home from work tonight in almost the same exact damn spot the light came on again. anyone know what could be causing this possible problem with o2 sensor? I hear this light type of whistling sometimes also from the bottom. i was going too just wait 3 weeks or so till catback pipe comes in and when i remove the stock tell them about it. any opinions would be cool. Oh yea when the light comes on the car doesnt change at all in response too anything. it will run fine and just pop on. lemme know thanks
