Do you have any codes in the ECM or an engine light on ? What have you done so far to attempt to repair your vehicle ?

This code is for the vehicle running lean ( more air than fuel ). If the vehicle is overheating it can set this code. You will have to check why the vehicle overheated. Low coolant/rad fan/ thermostat are all things that will have to be checked. The rattling noise may have been from EXTREME overheating and serious engine damage could have occured. Have a certified repair shop take a look and find out.

Sounds like the TPS(Throttle Positioning Sensor) or the IAC(Idle Air Control) is malfunctioning. Sometimes these sensors malfunction because of a dirty throttle body. You should clean the throttle body out with throttle body cleaner first. After cleaning the throttle body out, start the vehicle. It will be slow starting and when it does start it will run rough but after a minute or two it will settle down. You will need to clear the trouble codes. Most major auto parts stores will do this for little or no charge. After clearing the trouble codes drive the vehicle. If the vehicle runs properly, no more is needed. If the vehicle still runs the same as before then continue to drive vehicle until the engine light comes back on. Read the codes and replace the defective sensor.

I just finished fixing my 2005 Envoy with the same problem. Your problem is most likely a dirty throttle body. If you take it to a shop they are going to want to replace it for about $500. If you clean it, you can usually fix it for less than 10. There are a couple of good videos on youtube about removing and cleaning the throttle body. Some say not to touch the butterfly inside, but you can also pull the fuses for the fuel system, or do an idle relearn procedure after you clean the throttle body so the vehicle will run properly. Basically, you can clean the throttle body with throttle body cleaner after removing the unit from the intake manifold. You will need a flat-head screw driver, a 10 mm socket with an extension to remove the vortec cover/box that covers most of the engine. There is a wire attached to the left rear corner of the box and an evap hose attached to the front left corner of the box. Then you remove the plug on the throttle body, the fuel line and four mounting bolts and the throttle body comes off. Don't use anything abrasive to clean the part--just throttle body cleaner. Also Don't drop the part. These seem to be rather delicate and using abrasives or dropping the unit will damage the coating on the inside of the throttle body. I do recommend watching the videos.

After cleaning the unit, you may need to do a throttle relearn procedure for the system to reset. look these instructions up online or call a GM dealer. You may also need to clear fault codes while driving the vehicle for the relearn procedure. It took about 20-25 minutes to remove and clean the throttle body, about 15 to reinstall it, and then 200 miles to reset the OBDII codes on the computer. My vehicle also has a faulty fuel guage wich made completing the OBD tests take longer than usual. The repair is pretty straight forward--by no means worth over $500 at a garage!!

Good luck, I hope this helps

Have you tried to jump start the vehicle ,low voltage ? Loose battery connection's . Turn on the headlamps ,are they bright ,seam normal ? If headlamps are bright suggest you have it taken to a qualified repair shop that has a factory or professional scanner to hook up to the vehicle . Check for DTC'S - diagnostic trouble code's . The electronic's on your vehicle are complex , 10-15 electronic control module's ,serial data communication network for the control module's . Ignition switch is a low voltage input to the BCM - body control module .
Moving the ignition switch to the START position signals the body control module (BCM) that engine crank has been requested. The BCM verifies that theft is not active and sends a serial data message to the powertrain control module (PCM) requesting engine start. The BCM also energizes the RUN/CRANK RELAY. When the RUN/CRANK RELAY switch side closes, and the vehicle is in Park/Neutral or with the clutch fully depressed, if equipped, supply voltage is applied to the PCM CNTRL relay coil. The PCM verifies the transmission is in Park/Neutral or if the clutch is fully depressed, if equipped. The PCM will then ground the control circuit of the PCM CNTRL relay, closing the switch suppling voltage to the starter solenoid. On some vehicles the starter will continue to crank the engine with the key released until it starts, the crank command has timed out to prevent excessive heat build up in the starter circuitry or the PCM receives an engine run flag.

Take it back to the body shop
They are getting paid by the insurance company to,properly repair your vehicle
Don't loose sleep over it,make it their problem

That is either bad contacts inside of the master window switch on the driver side door, and you can actually take apart those old switches and clean up the contacts with an emery board type finger nail file, or the problem will most likely be a broken wire(s) inside of the weather boot that runs between the driver side door and the body of the vehicle. Try turning the ignition to the "Run" position and then move the weather boot between the door and the body of the vehicle around while at the same time holding a window switch down in the direction that you want the window to move, and if the window does work while moving around the weather boot then there is a damaged wire(s) that will need to be repaired, and any wires that you find broken should be soldered back together and do not use wire connectors to repair the wires. (However, if the wires are too far apart inside of the weather boot then this test will not show any results) and if there is no damage to the wires at the wire connector to the master window switch, then the wires leading from the master window switch out through the door and the weather boot will have to be inspected thoroughly for any damaged wires.

it resets itself.

Principles of Operation
The PATS uses a specially encoded ignition key. Each encoded ignition key contains a permanently installed electronic device called a transponder. Each transponder contains a unique electronic identification code out of over 18 billion, billion combinations.
The passive anti-theft system (PATS), also known as SecuriLock ®, uses radio frequency identification technology to deter a drive-away theft. This system is known as SecuriLock® in North America, Safeguard® in the U.K., and PATS in Continental Europe. Passive means that it does not require any activity from the user.
The SecuriLock® System (PATS) is not compatible with aftermarket remote start systems, which allow the vehicle to be started from outside the vehicle. These systems may reduce the vehicle security level, and also may cause no-start issues. If equipped the remote start system must be removed before investigation of PATS-related, no-start issues.
Each encoded ignition key must be programmed into the vehicle's powertrain control (PCM) before it can be used to start the engine. There are special diagnostic repair procedures described in this section that must be carried out if a new encoded ignition key is necessary.
This system contains a new feature named Unlimited Key Mode. This feature allows a customer to program more than eight keys to the vehicle if they request it. Each vehicle in Unlimited Key Mode is set up with a special Unlimited Transponder Security Key. This allows all the customer vehicles to share the same keys, but no other keys from outside can be used to operate the vehicles. For an individual customer, any randomly selected Security Key is acceptable. Refer to Unlimited Key Mode Programming in Key Programming Switch State Control in this section.
The PATS transceiver module communicates with the encoded ignition key. The module is located behind the steering column shroud and contains an antenna connected to a small electronics module. During each vehicle start sequence, the transceiver module reads the encoded ignition key identification code and sends data to the PCM.
The control functions are contained in the PCM. This module carries out all of the PATS functions, such as receiving the identification code from the encoded ignition key and controlling the engine enable. The PCM initiates the key interrogation sequence when the vehicle ignition switch is turned to RUN or START.
All elements of the PATS must be functional before the engine is allowed to start. If any of the components are not working correctly, the vehicle will not start.
The PATS uses a visual theft indicator. The indicator will prove out for three seconds when the ignition switch is turned to RUN or START under normal operation. If there is a PATS concern, this indicator will either flash rapidly or glow steadily when the ignition switch is turned to RUN or START. The PATS system also flashes the theft indicator every two seconds at ignition OFF to act as a visual deterrent.
The PATS will be activated and will disable the vehicle from starting if there is a:

• incorrectly encoded ignition key
• damaged encoded ignition key
• unprogrammed key
• non-encoded key (key has no electronics)
• damaged wiring
• damaged transceiver
• damaged PCM
