I'm a bit perplexed by this. Today I drove the SDL to the office and didn't notice anything. Got out of work and did a few earands. Got the front wheels balanced at my usual spot then I noticed it. At idle there is a strange vibration and sound. Its hard to explain almost like a 4 cylinder gas car with weak engine mounts. It is engine related, in N its still there, when in gear I can feel it more. It goes away over 1k rpm.

It almost feels like a collasped engine mount. The drivers side looks fine, now that the car has cooled off a bit I need to look at that pass one. I don't see anything out of sorts. It almost feels like the engine isn't firing right at idle, something is off and I can't put my finger on it. Bad fuel maybe? I'm down to a 1/4 tank. Still I drained the tank a few years ago and the fuel is always clean. I have never had fuel problems with this car, I always buy it from the same high volume place, but still.

Any ideas?
