exhaust leak before front O2 sensor causing detonation? I'm thinking the crackling sound coming from my motor is detonation. I have midlength headers and where the flange meets the little peice of pipe with the O2 sensor bung I can feel some exhaust coming out. In the morning, I'm gonna try and tighten it up. Could this be what has been driving me crazy!??
