Let me guess stubles and stalls when hot? That is what mine was doing. Look a few pages back for my "hesitation" threads. I got a cam sensor a couple of years back for around $75 from mazdastuff.com Sorry I dont know about a 96, but on my 99, it took around 30-45 seconds to install the new one. It is right on the top of the engine. Pass. side of the valve cover right in front. No problem since.
