Hi Steve,

Thank you for the input - I really appreciate your feedback since I'm about ready to push this car off a cliff!!! I'll set up an appointment at the Indy shop to check the same.

I really think that is the right area because it doesn't vibrate when the car first comes to a stop - it takes around 3 to 5 seconds. And, regardless of idle speed, you can feel the vibration when the car first starts. Finally, if driven harder, it takes a little longer for the vibration to start (maybe 7 to 10 seconds). This suggests that pressure of some type builds in the car and then gradually escapes while the car idles. When the car was at the dealer, here is what they did:

071171 Electronic Test Program - For Fuel Inj.
071172 Individual Compents with Fault Codes, Check
431051 Vacuum Hose to Brake Booster, Test for Leaks
071426 Fuel Injectors Hydraulic test Program, Perform
221019 Hypr Motor Mounts, check/Adj. for tension
221260 Front Engine Mounts - Left & Right Side, Repl.

MBz was alittle stubborn; I offered to leave all the paperwork so they could so what the Indy had done (which was 3 out of the first 4). I think MBz was headed in the right direction with the Brake Booster - they just didn't follow up on some other similar possible causes.

Anyway, with the work the Indy has done, I probably can get them to do this for free. How much did the repair cost?

Thanks,

John
