I am driving along on the highway and the motor dies. I coast to the side of the road, put it in neutral and it starts back up with no problem and I drive off. It won't happen again for a while.

Tell me is the check engine light on? How does it stall does it just die or does it loose power and then eventually die? It sounds like a crankshaft angle sensor.

Please run this guide.

Please let us know what you find. We are interested to see what it is.

The check engine light is not on. It is not gradual. It is like I turned the key off.

I took it to my mechanic and he said he connected it to his computer and nothing came up. Is that what you mean?

Ok that just means there are no codes we already knew that because the check engine light isn't on. Now what I would like to do is check the camshaft sensor.

I have a CarMD Handheld Tester. I don't think that's what you're asking for so the answer is no.

Ok we either need to get our hands on a digital multi meter or have the cam sensor checked. It could have corrosion on the plug or not be sending the signal correctly or? Here is a pic of a inexpensive multi meter. If you are not comfortable doing these tests please just let me know and I will let you know what tests I would run if you would rather have a shop do it ok.

Ok if you would have him unplug the camshaft sensor and ohm it. Get back to me with what you find and I will look it up to see if it is in spec.

I talked to my mechanic about ohm-ing the cam sensor and he didn't understand. So we replaced the sensor and that fixed the problem your hunch was right thank you so much for your help I love this site.
