Hi,

So, I finally bit the bullet and got my head gasket replaced for a large chunk of cash (seriously, my Forrester is too young for such things to go wrong!) and when I got the car back I immediately noticed the gas pedal vibrating. It vibrates when you first step on it and then again at about 2000 RPM, and then it goes away at higher RPM.

 

I said this to the guy and he was like "oh, it's the throttle cable" and sort of poked at that a little bit, but it didn't change. And then since it was 5pm on a Friday I decided to just take it home, but it's still annoying me.

 

Any idea what could be causing this?

The throttle cable is routed incorrectly, I'd put money on it
