If you are not mechanically inclined you may want to have a mechanic change it out for you. As for the cam position sensor this engine does have one, it can be an issue but it doubt it in this case. If you are so inclined have it replaced at the same time as the crank sensor.
I edited my original post with additional info. In short, replacing the CPS did not fix the problem. Could I get your feedback and any suggestions?
