I found out that its the crankshaft position sensor, I kinda figured that since I have been reading all of the posts here on this great website. Now I have a question. I want to buy a crankshaft position sensor and dont know which one to purchase. I have to drive the car back and forth to work everyday and cant take it out until I get the new one, so I can switch it out right away. I looked at this website and they have 3 different ones. how do I determine which one I need without taking the unit completely out? Can I go by the vin number? Any thoughts would be appreciated.
