i would first try to replace the fuel filter.usually there filter accumalates debris in the gas tank especially if you you ru the tank close to empty.filter location needs to be traced from the tank toward the motor.you will see a cylinder inline with a strap.part usually runs around 20.00. also when you initally turn the key before start you will hear a hum for about 2 sec. this is the fuel pump pushing the fuel up to motor.so if you hear this pump is working.
code p 0300 is random misfires ===causes ---plug/s--HT lead/s---injector/s---ignition coil/s---low compression ---wiring
replace the cat converters as they are important for proper engine tuning
the problem most likely is faulty injectors that over fuel , leak and need attention
you can fit a vacuum gauge into any vacuum hose to read the vacuum at idle ( 15 or deceleration from high rpms 25)
fluctuation reading at idle indicates problem valves

It sounds like a problem with the idle air control valve. However, the possibilities are too numerous to explore here. I suggest that you drive to the nearest AutoZone and get a FREE diagnostic scan and get back to me,
check for a vacumn leak, my buddy has a 96 dually that did that,found out it was his temp sensor to the computor,was showing a negative # when i tested it,he replaced it and it fixed everything! He couldn't believe it LOL
Start withe the cheapest fix first. When was the last time the fuel filter was replaced? Sounds like a plugged fuel filter but I would also check the air filter. It obviously has spark since it was running and if the air filter is clean then all that is left to check is the fuel system. When you turn on the ignition you should be able to hear the fuel pump cycle to pressurize the fuel system. If the pump does not make any noise, then hit the bottom of your fuel tank with a hammer. This will sometimes make the pump work again but should be replaced ASAP. Take off your air intake and look down the throttle body while someone else turns over the engine. You should be able to see the injectors pulsing fuel into the engine. Do you have a 3.8l engine? If so, they are notorious for the timing cover seals leaking. This means that antifreeze will leak into your oil pan and wash down your rod and main bearings. That means that your engine is in need of a rebuild.
I don't think an exhaust leak would cause the sputtering in all gears. I've run my Geo in the past with a cracked exhaust manifold for months, and it ran fine, just a bit louder. Are your spark plugs & wires in good shape (missing vs sputtering)? Also check inside the distributor cap for corrosion/carbon build up. If all that is ok, then I would start with the basics: first try running a complete fuel system cleaner through it for the next two tanks, that should clear any partially clogged fuel injectors. If no luck, then replace the fuel filter, and try it, if it still sputters you can check the fuel pump strainer if it looks ok, then you might want to replace the fuel pump.
As far as your sputtering when leaving from a stop, I have found that the bushings in the distrubutor wear out. The rotor will no longer be centered under the cap and it will result in a poor idle and sputtering. The best way is to remove the cap and rotor and check to see if there is a brown rusty colored dust present. If it is, you must replace the distributor and the problem will be corrected.
