i have a 96 outback with a 2.5... does the cam shaft sensor come out easily? do i have to remove the timing cover, belt and gear? or does it come right out the back? i hear that it is on the drivers side head, but i have not looked yet. some times the car starts right up, and sometimes it will crank and crank and keep on cranking. i give it a rest and try again. and sometimes it works and sometimes i have to give it another rest. anyway, just looking to change the sensor and see if it solves the problem. anyone have any luck changing theirs? thanks in advance.
