OBD-II the Cam Postion Sensor has to be "close" or the PCM cannot compensate enough, so it is somewhat critical to be adjusted correctly.
The process is easy. You need a helper, a toothpick or small drill bit, some basic hand tools and a "mirror on a stick" so you can see the timing marks on the bottom of the cover.
Remove the first spark plug and the camshaft position sensor.
Carefully place a finger over the spark plug hole.
Have your helper bump the starter a little at a time until you feel pressure.
(or use the straw)
Break out your mirror and check your timing marks.
Use a ratchet or wrench, 19mm I think, to turn the crank forwards to the zero mark.
Loosen the retaining fork that holds in the oil pump drive shaft that sits under the camshaft position sensor.
DO NOT REMOVE THE OIL PUMP DRIVE SHAFT!
Find the small hole in the outside of the housing for the oil pump drive shaft.
Find the small hole on the magnet inside that indicates camshaft position.
Carefully turn the housing on the oil pump drive shaft until you can align those two holes and insert a toothpick or drill bit straight through them.
Tighten down the retaining fork, reinstall the camshaft position sensor, spark plug.
