the sensor to replace is the HO2S sensor which is different to an O2 sensor. (has a different function)
code p0300 is random/multiple misfires
as misfires are from the electrical components you did not pay attention to items like low fuel pressure and faulty injectors which also cause random misfires.

check the engine family (4gh6 or what ever) later engines in the same family will fit and will probably have increased power. Problems may arise from the sensor s and the ECM as there may be differences. A good place to check out is google-type in your engine make and size and read wikipedia as they list vehicles with engine families and power ratings.

Yes and no.
It sounds like you have a wiring problem.
The alternator output could be 14 volts and only one or two amps, but that would be enough to kill the warning light. Its more likely the alternator is charging but the current is not reaching the battery.

Check the A/C Cluch . This is a common problem on today's Cars .
If that is not it , It is most likely your Idler pulley for the Serpentine Belt , once they get some miles on them or a little dirt they start to be trouble . Hope this helps!!! Grant

I would start by replacing the battery in the key fob remote that goes on your keychain. You can take it to most auto part stores and they will test/replace the battery in the device. It's a fairly cheap fix. If the device still isn't working after a new battery, then you will need to replace the fob. Some auto part stores like, AutoZone, will carry some of them but some you need to go to your local GMC dealer.

The gas pedal could beva drive by wire, meaning there is no physical connection between it and the engine. You did not say the year of your Envoy. If it is there may be a bad accelerator position sensor. If is not drive by wire you may have an issue with your engine. Either way have it checked by a technician that knows you make of vehicle.

Transmissions that are overfull can "whip" the fluid, buy catching the fluid on the rotating parts. This is bad for a number of reasons,, It causes air to be trapped in the fluid (foam) causing a loss of the ability to transmit pressure to the apply devices, they hold the clutch packs and bands, and move pressure control valves, causing a slipping condition. this in turn causes damage to componets and a great deal of heat, also very bad for the transmission.

On the 2006 model, if you have the steering wheel with the on wheel buttons, keep pressing the i button on the bottom right until you reach Display Units: If it says Metric, press the carriage return button to switch it to English and there is the solution.
