Hello Guys and Gals, got a CEL and I was looking for some advice:

Drove the car as usual all day long. Normal driving conditions, sunny, 60 degrees, occasional VTEC use mainly highway cruising.

Parked car and it sat for about 4 hours while I ate dinner and visited with my folks.

Returned to start car and the CEL came on immediately at start up.

Car runs the same as it always has...no hesitation stumbling etc.

Car is BONE STOCK. No intake, exhaust, etc.

Took the car to Schucks and they used thier scantool to pull the code and it is the P0411.

Did research and found that this is very common on cars after intake installs because people mix up some vacuume line routing.

I was unable to find it happening to people who have not made any mods or even been under the hood doing anything.

Any and all help is greatly appreciated

 

Having no CAI doesn't mean you shouldn't still trace the vacuum lines anyway. There have been several owners of stock cars where one of the vacuum lines have "mysteriously" fallen off or a hose connection has cracked and broken off. Also, the wiring harness has been known to be disconnected, again, in a mysterious way.
Go trace the lines, check valve and wiring harness.
