The codes mean as follows
PO300 multiple cylinder misfires
PO301 #1 cylinder misfire
PO308 #8 cylinder misfire
Some of the more common causes for these codes popping at once are, if you went through a big
puddle and the engine and wires are wet or the distributor cap and/or wires are bad or the camshaft
sensor(located inside dist cap) is bad and sending false signals. Hope this helps.
P0300 is a generic code telling you that your engine is misfiring. 301, and 308 are cylinder specific. telling you that number one, and number 8 cylinders are misfiring, the cheapest easiest place to start if you haven't is plugs, wires, cap, rotor, etc. just a major tune up thats usually due on a 10 year old vehicle,

A code P0500 may mean that one or more of the following has happened:
1.The Vehicle Speed Sensor (VSS) is not reading (functioning) properly
2.There is a broken/frayed wire leading to the vehicle speed sensor
3.The vehicle's PCM is not correctly configured for the actual tire size on the vehicle
The simplest thing to do is to reset the code and see if it comes back. Next, check all wiring and connectors that lead to the speed sensor. The location of the sensor depends on your vehicle. The sensor could be on the rear axle, transmission, or perhaps the wheel hub (brake) assembly. If the wiring and connectors are OK, then check the voltage at the speed sensor.
