DTC P0300 - Random/Multiple Cylinder Misfire Detected Basically this means that the the car's computer has detected that not all of the engine's cylinders are firing properly.
A P0300 diagnostic code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why.
Symptoms may include: the engine may be harder to start the engine may stumble / stumble, and/or hesitate other symptoms may also be present
A code P0300 may mean that one or more of the following has happened: Faulty spark plugs or wires Faulty coil (pack) Faulty oxygen sensor(s) Faulty fuel injector(s) Burned exhaust valve Faulty catalytic converter(s) Stuck/blocked EGR valve / passages Faulty camshaft position sensor Defective computer
DTC P0340 - Camshaft Position Sensor Circuit Malfunction This fault code indicates that a problem was detected in the camshaft position sensor circuit. Since it says circuit, that means the problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM. Don't just replace the CPS (camshaft position sensor) and think that will definitely fix it.
Symptoms can include: Hard starting or no start Rough running / misfiring Loss of engine power
A code P0340 could mean one or more of the following has happened: a wire or connector in the circuit could be grounded/shorted/broken the camshaft position sensor may have failed the PCM may have failed there exists an open circuit the crankshaft position sensor may have failed
If need additional details, feel free to contact us in the fault code links. Hope this helps.

P0300 is a random misfire and P0316 is misfire at start-up.
If you have the V6, I would start by replacing the plugs and all the coils.
This is a little ******* the V6, since you have to remove the intake manifold, and the coils can be expensive. Coils are available on Ebay.
I've replaced all the coils on my 2002 Escape V6 after 100,000 miles. Typical V6 problem.
