I recently purchased an 02 LS V6 and had the emissions system repaired and while removing the main air intake unit (the large black plastic unit in the immediate front of engine, don't know the specific technical name for it) there is a T-shaped connector/hose/airline coming off of the unit about dead center which connects to large openings on both sides off the upper engine near where the plugs are located. The passenger side portion broke completely off and now I'm getting P0174 and P0171 codes for Bank 1 & 2 (lean). The codes refer to PCV valve and hose, etc., but this piece is NOT the PCV hose. Does anyone know what this piece is called and where can I purchase it? It simply plugs directly into both sides of the engine and the air intake unit by snapping in, no tools are needed whatsoever, but I can't pass emissions without it. Thanks.
