Nissan 370Z Forum - View Single Post - Just installed Stillen CAI, got some codes

Most common causes of those codes are: dirty MAFs and air leaks. Google is your friend.

Since you've cleaned the MAFs, look for an air leak. While the engine is running, hold one end of a paper towel tube (or similar) to your ear and move the other end around near the intake piping to locate the leak. Follow all safety procedures when working near a running engine.

Edit: If it's not a leak, then check the wiring going to the MAFs.
