Along with the mystery codes you should get a good idea of the cause, continued use when showing this code can cause damage to the engine.
Come back with the mystery codes and you might get better help.
Check the plugs and cables if you want something to do.
P0300 is a random misfire code, it just means more than one cylinder has been deactivated- The other codes change, sometimes they are p0301 and P0305, other times its P0304 and P0302, but those codes just tell me the car has shut off fuel and/or spark to a specific cylinder... So getting a P0304 code only tells me that cylinder 4 was shut down.... but it doesn't tell me why. The fact I'm not getting a consistent and repeated P030X code is what makes me think it's not plugs, coils or wires.
I will start By checking fuel pressure tonight and keep you all updated.
By the way, it's really great to have such passionate and helpful Crossfire enthusiasts at my fingertips... You guys are great!!!
