My '03 Coupe has been throwing these codes lately (I'll be taking it in tomorrow to have the dealer look at it). It occurs on startup when the engine is cold, usually after a "shuddering start" due to the wonderfully un-smooth CC launch, particularly in reverse. Usually P0300 (random misfire) and P0303, P0306, and P0308.
Anyone experiences something similar? Any resolution? My first thought was that the shaking on starting off was triggering a false detection, but now I'm not so certain. Clearly there is a power drop after this occurs.
I can start the car up warm generally without issues. I'm starting to get concerned about the groaning noises the car makes when taking its first few steps in the morning. Is this a normal sound? Sure doesn't seem like it should be...
