    Your thoughts on this scan

    94 Firebird LT1 - keep having some issues with hesitation. Take a look at this pic of a scan. It hesitated around 500-520 seconds Would you say my left O2 Sensor is bad?

    Either that or one bank of your engine is having serious mechanical issues. O2 sensors are cheap and easy to replace, throw one in there and see what happens I says.
