exhault pop ?
exhault pop ? when I get out first gear to go second, I heard a pop on exhualt, and if i rev the car up, I also heard a pop. got full exhualt from header to pipe, so cat. Is this normal for lt1 ? i heard lt1 exhualt is pop.
could be an exhaust leak, which can cause your o2 censors to compensate for extra air in the exhaust by giving the motor more gas-resulting in a small explosion from unnburned/too much gas in the exhaust.
