Error code P0300 means that you are having multiple/random cylinder misfires. I would start with changing all of the spark plugs and see if that will fix it. You will have to have the code reset at an auto parts store. If that doesn't work let me know and we can progress down the line.

I don't think it could be the injectors. Because, all of them would have to go bad at the same time to give you code P0300. If one injector when bad on number one cylinder, it would give you a code of P0301 for cylinder #1 misfire. Code P0300 is the computer simply can't determine the specific cylinder of misfire. Basically,
I would look at the EGR system, engine timing, and fuel pressure. One of these should be the source of the problem.

look inside the disturbutor cap and see if there is white build up on the points inside the cap. if so change cap rotor plug wire and plug. go from there.

Check the oil,smell the oil,to see if there is a gas smell to it,if so,the injector spider,has a broken injector line.The intake will have to be removed to replace the injector.

This is a misfire.....Start with the least expensive thing....First thing to try is change your spark plugs to A/C Delco 41-103's. If this doesn't clear the code, you probably have a bad coil which can cost around $70 each.
