Hey everyone, on my 2014 with 170k I get an occasional slight pulsing/shaking through the cabin while in drive at idle. Couldn’t identify a scenario that triggers it. Anyone else experience this or any ideas on why this is happening?

What gear? Same in N, D or P? With or without compressor running?
Service history? When were the spark plugs and fuel filter last changed?

Leederosa

In Drive. It’s been with the compressor running but not sure if it happens when off. It comes and goes randomly and the compressor has been on when it happens. Plugs changed a couple weeks ago. Don’t know if fuel filter has been changed yet. Purchased used.

Have the Motor mounts checked.

Leederosa

Thanks, that’s helpful. When the motor mounts start failing, does it happen intermittently?

I'm not sure it is related to spark plugs, but it is an option to look into them

Has the battery been disconnected recently for any reason? Chances are a quick cleaning of the mass air flow (MAF) sensor and/or the throttle body will likely correct things.

Does the idle suddenly drop down and feels like the car is going to stall?
If it is, my 3rd Gen GS used to do that, and it's normal.
