Hello I hope I can help, I've been try to find My Tempeture sensor and I came across the PCV valve It's located on the top of the engine on the passenger side. If you change your spark plug wires you go right by it when you send the rear wires to the back. It located in the back side of the engine on the passenger side. You'll need a light. It's there OK! be positive.
