SOURCE: HI! I have a 2005
Could be one of three things:
If the check engine light is coming on intermittently, it could be your gas. You should be using 91+ Octane Gasoline (put some octane boost to see if it smoothes out, it's about $4.00). You should be putting in Chevron/Shell/76 gasoline, not the ARCO/AM-PM gasoline. The top tier gas has additional cleaners.
Could be a bad coil not triggering one of the spark plugs.
Could be the camshaft position sensors.

Code PO340 "Camshaft Position Sensor Circuit Malfunction". Now that does not mean that if you simply replace the sensor your problem will be solved. It can be simply loose, cut, or corroded wiring. It can also be something entirely different. This is where diagnostic skills come in.
