I have a 2003 L-tuned IS300 with a couple of mods. For some reason I go to drive my car today and my check engine light goes on. So when I got back home I noticed that one of the tubes from the SRT intake disconnected so I put it back in its place and for some reason I think one tube might be missing. Problem is I don't have intructions of the intake around anywhere so can't really tell. I searched online but cant find any good pics of the intake installed. I was wondering if anyone knows if a tube connects to the bottom left of engine cover where something really thin sticks out, because I remember one being there? I'll appreciate any input or suggestions, thanks. By the way if anybodies wondering what I believe caused one tube to come off and possibly one to dissappear lets just say I have plenty of cats around the neighborhood and usually find them under my car on a cold day.
