hey all, I'm having trouble identifying two small plastic feeling lines that run over top of the transmission and into the rear of the enginge bay, right where the spark plug wires sit. does anyone know what these lines are? mine aren't connected to anything in the engine bay side. I will attach a picture as soon as I can. thanks.

The way you describe them it sounds like the breather tube lines.
