2001 Boxster S w/ 133k miles on it. Recently developed a funny idle. Car drives fine, but feels like cars going to cut off when idling. It hasn't, but just sounds like it is, kinda like the old cars with the carburetors. Here are some clips of the engine and exhaust. Also threw P1411 and P0410 codes about a week ago.
