Okay, well yesterday I brought my car to my neighbor's friend's shop... because of how my car was shaking when idle (some of you might remember), well everyone i talked to thought it was a tune-up... and come to find out it was the EGK valve... and I have no idea what that is, so I was just wondering if someone could enlighten me... thanx

I'd believe an EGR (Exhaust Gas Recirculation) valve.
