...gas mileage or my O2 sensor? Im fixen to put a new exhaust on my truck and i need to know if cutting my cat off will interfere with my gas mileage or O2 sensor.
Well again i have a 2001 yamaha yz 85. It set in the barn all winter, and this spring when i went to ride it, it runs but it dosent run right. Once it gets wound up and starts to want to hit its powerband, it just stalls, and goes brep brep brep. Plz help
