Motor mount Question

Yes...I have a terrible vibration below 1100 RPM's. How do I determine if I need new motor mounts or if it is a problem with the timing belt slipping a notch? What is a fair price for motor mounts and where?

That's a very easy fix. DRIVE FASTER. Seriously though, if I have my idle set at maybe 950 the car shudders at stoplights. So I upped it to 1100. Try raising it to 1150 or 1200, or lowering to 1050. Sometimes a certain RPM sets up just the wrong frequency on your car and it has nothing to do with motormounts being old. I could be wrong, but hey, try it.

Motor mounts are rather in-expensive, it's the labor that get's ya. We recently did a right side mount along with some other services. When I break out the costs, it comes in at about $200, including the mount. If you re-set your idle, you are only delaying the problem. Take the time to have it checked....

If the vibration goes away above idle, it's the motor mounts. Mine did it.

My engine runs quite smooth at anywhere near idle, specially when warm... I mean the engine, I'm not saying the car doesn't vibrate, (it doesn't!), but when I put my hand on the (for example) intake manifold, it's amazingly smooth, as smooth as say my parents Honda V-6... (naturally balanced, beautiful engine, too bad it's not a stick).

Just letting you know, the reason you feel the vibration is the motor mounts, but the reason the engine vibrates is NOT.
