I got an 00 with 106k mi
car shakes slightly at idle
Is this a common problem?
what can be causing this?

I do have new motor mounts and spark plugs installed so thats not the cause.

Usually if its not motor mounts its ignition related, could be bad spark plugs or bad spark wires.

Before the headers = NO

After headers = YES

The reason = Have no clue ;-)

Put it on the computer for a check up, I would say time to change your plugs.

I'm in the same boat, but mine does it in Park, never in Drive. I have new spark plugs/wires and new motor mounts.

I have it... a few other E55 owners had it too. I see it as common.

mine does when its cold. once warm it doesnt shake at all.

Every older NA 55 I've gotten into has had the shake. Adding a full can of seafoam into half tank of gas definitely helps get rid of alot of the vibration but it does not cure it over the long run. It can be anything from MAS to bad O2s to plugs/wire to dirt injectors to bad mounts. Best way is to just move systematically from the cheapest maintenance option to the most expensive until its cured.

Mine is opposite, when it cold it so run so smooth you wouldn't know the engine is running.
Even when it warm as lone as it in drive it very smooth but once you put it in park the engine vibrate/shake

I get it if I haven't driven in a few days at the first time I come to a stop. None after that. And its barely noticeable even then.
