Well you need to take it in you likely need to have your injectors and coils replaced. If you lived down near me I could send you to my dealer that looks past mods. You will need to pull the Jb3 off depending on how your dealer is and maybe the DP's.

The codes say you ran low on gas and the motor knocked/misfired. Could be a fuel delivery issue like FP as well.

I do not see it being the JB3. These cars have issues with the Injectors and coils and if you run the tank too low it can cause these things to happen.

so the knock is caused by the injectors, coils, or the tank being too low?

How many times did you run the tank low like that?

Well it could of been caused by the gas itself being crap. Knock can happen for various reasons like low octane or poor quality gas. If it is running too lean then it will happen as well. The best thing is just to get it to the dealer ASAP so they can fix it.

hm....well i always use chevron no matter what so the quality i think is there. i deleted the codes and will try to recreate them, which i know i can (4th gear during a WOT pull has thrown a light twice in the past week.)
