Injen CAI Code P0411
I have just purchased a 2001 Honda S2000 with an Injen cold air intake. It threw the code P0411, so maybe the two are related. As far as I know that is the only modification done to the car. Any advice on how to fix it? I'll need detailed help as I am not very experienced. Thank you for any input.

I've seen this code before. When I took the intake box out to clean it. I forgot to hook up a vacuum hose. Listen for sounds of a vacuum leak. I believe the code is coming up because one of the hose might be hooked up backwards or there might be a tear on the actual hose itself. I hope this helps

It looks like the top vacuum line coming from the fuel rail is connected correctly but the lower one might not be connected to the solenoid at the right point. I'm talking about the solenoid that is attached to the intake arm. Try swapping the vacuum lines on the solenoid. Not sure if you have to clear the codes or not.
