Heh join the club...I have a light as well.

I would check to be sure everything is hooked up and in top condition-fresh plugs, all wires connected, etc.

Might even be some bad gas-I'm not sure.

I haven't had mine read yet so...but I just started it for the first time after doing a cam swap...:)

Could it be a bad O2 sensor?

That's a definite possibility Jasin. When I put the Power Effects on, I think I remember seeing the drivers side O2 sensor looked slightly melted. You might want to check that. Very easy to swap out and fairly inexpensive. I'm rackin my brain tryin to figure this out for ya.

would the o2 sensor make the P0300 code though?

Did you check all the vacume tubes and throttle body gasket yet? I think if it were the o2 sensor the car wouldn't run right, but you never know.

Having a bad O2 will screw your idle, and your gas mileage. That is what it did to me.
