My name is jake. I have an 06 Audi A4 2.0t and its having problems. When I start the car it idles low and accelerates slow and Rumbles. I took it in and a code popped for a misfire in cylinder 2. So I replaced cylinder 2's plug and its still doing it. Any ideas? Could it be a coil?

 

That would be the next item to replace. One test before buying a new coil module is to swap it out to another cylinder and see if the mis-fire code follows it. Say you move it to the number 1 cylinder and you get a mis-fire code on that cylinder, you'll know the coil module is bad.

A mis-fire on one cylinder on a 4 cylinder car is more noticable than say a 6 or 8 cylinder.
