Have a 03 infinity fx 45 and I purchased it for fairly cheap. Due to sluggish idle and rough driving. Replaced spark plugs and ran alot quieter and then drove it around town for about an hour and it just started making a chugging noise and then it stalled it will not start now . Error code coming up are p0340 and another code with something about the wrong key being used or key fob battery. Can't find the piece of paper with codes right now. My brother bought and replaced 3 camshaft position sensors and still had rough idle and chugging noise . I bought the car and code p0340 still arising . He mentioned something about a sensor that had a green toggle switch on it that was kind of iffy and was sitting loosely in the engine. Looking for help or tips on solution or if anyone knows of similar issues and possibly looking for diagrams of the engine as I'm just learning about this style of vehicle. Not mechanic at all but a mechanics daughter so I have a little background and alot of ambition to repair myself .
