p300 is random misfire which may or may not be the issue with your plugs/etc.
the other two are weird the sensor two circuit has nothing to do with lean or rich.
P1137 - Heated Oxygen Sensor (HO2S) Bank 1 Sensor 2 Lean System or Low Voltage
something wrong with the wire to the trans or something in the trans
P0741 Torque Converter Clutch Solenoid stuck off

p0300 is the misfire. p1137 is the O2 sensor reading a lean condition, probably related to the misfire. p0741 is TCC stuck off, which may be related to your traction control (although I don't know how).

The last time I came they showed me that some of my spark plugs were worn down would tht have anything to do with it?

When dealing with a misfire, the first thing you should always do is make sure you have good plugs and wires. If you have reason to believe your plugs have some deterioration they need to be replaced.

I had same problem on 2000 cavalier 2.4L. It would run fine at part throttle but missed when engine was under load. Also engine missed worse on cold days. After 3 coil pack/module swaps I got one that worked. I suspect it was the module-not enough voltage to coils. I wonder if module gets corroded inside after so many years-kinda like the resistor on the heater blower motor.

The firing order is 1-3-4-2 you have to watch because the misfire may carry over into the next cylinder. What cylinder is miss firing MORE? a TECH 2 can see counts so if cylinder 4 has a 1000 counts and cylinder 2 has 100 more then likely your "bad" cylinder is 4. As stated before if you question the plugs get some new ones. Sometimes I forget that not everyone has access to a Tech 2 so I do apologize Im just trying to give you the best info I can and relate to what I see in the field.
