For full features; Go to Mazda RX-8 Vibration While Idling
I have a 2005 Mazda RX-8 GT Shinka addition, with an automatic
transmission. There is just over 60,000 km's on it. General location is
southern Ontario, Canada. For the past 3-4 weeks, I have noticed what I
seem to think is excessive vibration in the car while the car is idling at
a traffic light or stop sign etc.
It's not like the entire vehicle is vibrating or shaking, but it is enough
that the steering wheel, driver and passenger side mirrors, and rear view
mirror are visibly shaking to some extent. Vibration can also be felt in
the driver seat. The check engine light is not on, and there are no other
warning lights coming on to indicate any kind of serious issue.
It also does not start this vibration immediately after ignition, but only
after about 5-6 minutes of driving. Another interesting thing is, if I am
idling at a light or whatever, and it is vibrating, if I put the vehicle
into Neutral, it immediately stops. If I put it back into Drive, it starts
again. Additionally, there are no issues while the vehicle is in motion,
everything runs smooth.
I have taken it in to a local Mazda dealership, and they could find nothing
wrong. They checked the computer, and everything was normal. They went over
the entire engine, and said it was in excellent running condition. They
inspected practically everything else on the car including engine mounts,
brakes, suspension, exhaust hangers, axles, transmission, etc and said that
the vehicle is in excellent condition.
Am I being extremely picky about this, or can someone suggest a possible
cause / solution? I know that prior to the 3-4 week period that this
started happening, that I had never experienced this issue in this vehicle,
so I know it can't be normal.
New spark plugs were put in last fall, and oil is changed every 4-5 months
by Mazda. I'm really leaning towards something transmission related here,
because of how throwing it into neutral stops the issue. Any suggestions
would be appreciated.

I would bet it's the engine mounts, I know Mazda checked but still
