Can anyone tell me where the pcv valve is located? Also, it has a hard time starting. It cranks over for 4-6 seconds then I have to stop and crank it over again before it will start. ?????

 

What year is the Tribute and does it have the 4 cylinder or V6 engine.
Does the hard start happen all the time or only after it has sat for several hours or overnight? Try this and see if engine will not start up right away. Cycle the ignition key slowly from off to run 3 or 4 times and then try to start up engine. Does the engine start right up after doing this key cycling?
