GM code P0300 indicates that one or more cylinders are experiencing misfires. ... Many times P0300 occurs when there are worn out spark plugs, spark plug wires, or a faulty ignition coil.

the service engine light is prob due to the oxygen sensor being damaged, not replace or you having the catalytic converter taken off---just messing with you. start at auto zone and have then do a free code read then go from there. you should troubleshoot the low fluid level switch for your brake fluid. unplug it and see if the light goes off and if it doesn't jump the two terminals on the harness. oh the car will have to be running.

if the check/service eng soon light is on a problem has occurred in one or more of the electronic systems of the emission system/engine management, it is very rare you will feel anything, the system has very good failure mode programming to keep that from happening, at this point the only thing will be that it won't pass a smog test, or the mileage may be affected. Have a test run to see which codes are present in the computer memory.

If your battery starts turns the engine over, it is doing it's job well. It sounds like your engine computer is not liking the cold engine. If it has been a while since a tune up, it would not hurt to go ahead and do it, but if it runs ok after it warms up, I sould not worry about it a whole lot. When the engine is cold, the egr valve and other things that are made to limit polution tend to stick and give the computer bad readings. A serious tune up may fix it, and I think should, but you MAY still be in the same boat! That does not FIX it for you, but should ease your mind on the light.

Like to other guy said, give it a tuneup. Also try SEAFOAM to clean carb up of slug. Also check to make sure the butter fly for the choke has not come loose, causing it the choke it down. Failed choke pull-off.
