Here's a link to your code problem,P0300 is their's a misfire and every number after 300,like 301 means cylinder one,which this is for both of your codes,go down the list and see if it's your problem.These codes have many faults,have to trouble shoot to fix. P0301 OBD II Trouble Code Here's the P0303 code. P0303 OBD II Trouble Code

P1599 - means that the computer detected that the engine stalled when the ignition had not been turned off.
Does your vehicle have a stalling problem?

P2138 - is the Accelerator Pedal Position Sensor 1-2 correlation.
The accelerator pedal has a sensor and the throttle actuator has the one as well. the computer expect thats both sensor will read the same as the accelerator pedal is operated. If one sensor read differently from the other the computer will set this code.

Long story short, you'll have to have shop to check this code out for you since a scan tool will be needed in the diagnosis of this code.

I have the same problem with my 03 Vue. I found some people saying that you can install a bcm on your own and by turning the ignition on and off in a certain sequence it will program itself. However I personally am going to take my car to a dealer. You can try to find a shop that has a tech 2 scanner (gm specific scanner), but it's not easy to find.

you have a bad computer my friend. nothing you can do but order up a new or remanufactured computer. try all your local parts stores. when you get the computer you will have to have a shop reflash it for you.

p1515,p1516 and p1271 What do these codes mean specifically? I'm lazy, I'm not researching that

I believe those are misfire codes on your cylinders. Tune up may be needed.

Before you replace the sensor, you should check the voltage circuit for the heater. The sensor may be fine and not getting voltage to the heater inside.
The code 1599 just means the engine has stalled at some point. It does not tell you why or how.
I doubt the two codes are related.

You want to make the light go away?

You have no interest in properly
diagnosing and repairing a system
malfunction on your vehicle, that
set the light?

You referring to clearing codes

There are no resets on vehicles

Here is the definition of the code in GM manual:
P0128 - Coolant Thermostat Below Thermostat Regulating Temperature, this indicates the engine is running cold, u need a thermostat
