The LL8 (or Vortec 4200), is a straight-6 gasoline engine produced from 2002 to 2009. It was the first Atlas engine, and was introduced in 2002 for the Chevrolet TrailBlazer, GMC Envoy, and Oldsmobile Bravada. The engine was also used in the Buick Rainier, Saab 9-7X, and Isuzu Ascender.

11.2 quarts from dry, including torque converter. When just changing the filter, between 5-7 quarts. Dexron 6 is the best, and newest technology from GM.

You have an inline six engine and it is equipped with engine-mounted electronic Powertrain Control Module that records hundreds of measurements per second and makes immediate adjustments of air, fuel, spark control, and valve timing to provide optimal engine operation. Your Vortec 4200 uses an electronic throttle control (ETC). The ETC sends a series of signals from an accelerator-pedal module using a sensor that relays acceleration-intent data to the powertrain control module (PCM).
To increase idle you will have to reprogram the PCM using an OBD 2 software. Have it service at your dealer.

you may have a bad fuel pressure regulator replacing it should stop your problem.

Firing order is as follows 1-5-3-6-2-4 for the Vortec 4200 series engine.
