Well went out yesterday for some cold air runs. Did not even finish the first one before she started breaking up on me . Brought her home had misfire in cylinder#4. I had been getting random cylinder #1 misfires so I was like WTF. Anyhoot luckily I had some parts from ECS waiting on my door step. Swapped out the plugs (RS7) and coils (RS3) and no more misfire. Runs like a champ!
