Code P0340, it makes like a lifter noise for like 30 seconds?

Code P0340 - a problem with the electrical wiring of the circuit to the camshaft sensor. So, I would look at the electrical connector for the camshaft sensor, here is the location of the sensor so you can check it out. Also, you might want to try a bottle of Lucas oil treatment, we have good luck with it.

If the connection seems okay, I would replace the sensor. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem.
