okay, thanks for the info. both would be vanos related.

I need to get my head under the hood while my wife is throttling it. To date, I have only revd it with hood upen and did not hear anything. It is all vibration/rough feel in neutral in the 1800 to 2000 rpm range and, while driving you can feel it in the seat of your pants, making me originally think pressure plate/clutch issue (149k and holding out on clutch as long as I can).

Odd I can only feel it in neutral and on downrev while in gear, and smooth as silk all other ways. Getting 29.4 MPG at avg speed of 46mph over the last few weeks of this issue? Actually, a little better than my normal 27.6mpg average but, I attributed mpg increase to new michelin's, RTAB's, FCAB's and alignment...not running lean for some engine issue?
