    Pre-Cat O2 Sensors (If's & Ands & Butt's)

    So I need to ask,,,
    what is one of the pre cat O2 sensors on a Ls1 stock motor is bad, what happens to the driveability of tha car.
    Would the car still run great with a little hesitation at idle,,,yet still burnout in 1,2,3 gears,,,
    Or if one pre cat sensor was bad would car go into that limp biscuit default mode?

    I wonder this since I get a P0300 code and all plugs are getting sparks..

    Generally a bad 02 sensor will make it run poorly, but if you're only getting the 0300 I wouldn't suspect 02 sensors. Do you have any mods, is it a stock tune, et.c are the questions to start with.

    check for egr leak at the manifold. Mine did the same thing and it had a small crack where the egr tube is fused to the flange where it seals to the intake manifold. Regardless, it sounds like some kind of small vaccum leak.
