My engine is a bit rough on idle. I have come down to a vac, or some sort of damn leak, or engine mounts. I tested the engine mounts, they seem rock solid. I still think a visual is not good for diagnosis and might have to do them regardless.

So yea, the car is almost 78k miles, and I am doing a tuneup really. I was googling rough idle and an E46 thread came up where the person replaced them and the car got better. For $17, I am not going to think twice about it, and figure its a cheap attempt at fixing the roughness.

Plus it's much easier that even finding the CCV, which I just want to inspect and clean really.
