Hey guys. This is my first post so sorry in advance if this is something that's already been asked before.

I have a 2001 NB8B and recently I've had a bit of shaking and vibration when sitting at idle at the lights for example but the revs stay steady at about 850. My temp gauge has been moving down and back up also a little by about 0.2-0.3 of a millimeter while also sitting at idle. Anyone had any troubles with this before? Any advice would be awesome.

Thanks guys.

Ive got the exact same model and had a similar issue, I used subaru upper engine clean and gave it a full service and it went away

I'll give it a go next time im free. Thanks for the info!

Next time it happens, jump out and tap the coil pack at the rear of the motor.
Can happen at idle with a bad coil pack.
