Actually I might still do it, The spoiler will just go back on until my buddy can work out the sh1t in the paint.
No idea, it actually might be the coils now. I swapped them and the plugs at the same time. I went from 104s, to 605s, and not back to 104s. I pulled the plugs and they didn't look fouled, but it still doesn't feel right.
So tomorrow it'll be spoiler then plugs and coils.
