When you change sensors be sure to use OEM parts. Others fail right out of the box and you move on thinking you put new in and that should be good when it's not.

The CKP crank sensor should have a paper gasket on it when installed to set the gap. Without it the sensor is damaged within the first few starts.


Are you overheating? Any codes or sputtering before stalling?
