It like when you have a shiver in the winter time.

be stop at a light bor stop sign and rpm will drop and come right back up. It is like the car does shiver like when you get a chill you schiver to shack it off.

the dealer just changed the oil about a month ago

The mirror itself is ok, and the electronics work, it's the housing that needs replacement. I got one from the dealer, but with no instructions.

I've had my Subaru for a year with no problems and all of a sudden this week I now have severe, oscillating noise/interference on my audio system that is directly tied to how fast I am going. When I go slow, the interference wipes out the audio - when I'm going faster the oscillation is so fast that I can still hear. When I stop, it goes away completely. It doesn't start immediately when I turn the car on - it takes a while so i'm wondering if something is overheating (electronics) causing this?

How do you replace a burnt bulb (Low Beam) on this car?
