I am pretty sure it is, if you leave the car sit over night is that back plug wet wih gas? Mine was wet with gas when it sat overnight witch points at a leaking fuel injector. I even switched the coil that was on The plug with the wet plug & it did not transfer witch shows it was not the coil, also switched out the plug and it still got wet with gas. I have a appointment Tuesday with my dealer to get the fuel injector fixed and will update this thread.
