help changed braks, now misfires?

[NeubsA4]

Just changed my brakes and rotors in the front. Then, I went to take it for a spin around the block to break them in a little bit and the car begins misfiring. I just changed the coils less than 3 months ago so it shouldnt be them. Coincidence?

If there is any connection between the brakes and misfires I would be amazed. If you can get the codes I'm sure you would get lots of answers, my friend changed his coils and a few months later 1 blew so I wouldn't rule that out.

Check if any coils are sitting higher than others. One could have popped out. Very random but not related.

well i have two coils coming from the dealership to have extra just in case that isnt the problem. pulled out coil from cylinder one and it is putting out very weak spark. hopefully thats the problem. thanks guys!

Weak Spark? Is that even possible?

Usually Coil Pack work or they don't work.

well when the coil is completely out and the car is running its much much worse than when the coil is in. but when i have the coil out you cant see any spark

[NeubsA4]

ill let you know if it works when my brother drops off the new coils for me.

How can you see a spark? Spark plugs make sparks, not the coils!

cylinder 3 coil went bad. 3 month old coil. wtf! ha guess you were right. thanks!
