Are any DTC'S - diagnostic trouble code's stored in any module ? BCM - body control module , PCM - engine computer ,IPC etc.... It's the temp. gauge not thermostate gauge Did it work after replacing the thermostate an coolant temp sensor ?
Engine Coolant Temperature Gage
The instrument panel cluster (IPC) displays the engine coolant temperature as determined by the engine control module (ECM). The IPC receives a serial data message from the ECM indicating the engine coolant temperature. The engine coolant temperature gage defaults to 38°C (100°F) if:
• The ECM detects a malfunction in the engine coolant temperature sensor circuit.
• The IPC detects a loss of serial data communications from the BCM.

The first thing too do would be to hook up a factory or some other type of professional scan tool an see what the temp. sensor is telling the engine computer an if the BCM is showing the same temp. data . And is that info. getting to the instrument cluster . Knowledge of how it all works an proper diagnostic technique is the key to finding the problem .
If the IPC is see same temp the engine computer is an the gauge isn't working something is wrong with the gauge itself. New instrument cluster would be needed .

Check engine light lit or yellow wrench symbol ? Any DTC'S - diagnostic trouble code's stored in any module on the vehicle ? Hooking up a professional type scan tool an doing a full system diagnostic would be the first step to find the problem ,not asking for assumptions (guesses) on here .Your best bet , have a qualified repair shop check it out .

Low Beam System Operation
The headlamps may be turned on two different ways. First, when the end of the of the turn signal/headlamp switch lever is turned to the second detent position, the headlamps will illuminate. A ground signal is provided to the DRL control module. The module then provides a ground path to the coils of the HLP relay. Since the head relay is provided with battery voltage to both the contacts and the coil, the coil becomes energized and closes the contacts providing voltage to the DIM relay. With voltage and ground provided, the low beam lamps light. Second, with the switch in the OFF position, for automatic lamp control (ALC). During ALC the headlamps will be in one of the following modes of operation:
• Daytime running lamp (DRL) operation in daylight conditions, refer to DRL below for the operation of the circuit.
• Low beam headlamp operation in low light conditions. When the ambient light sensor senses a low light condition for approximately 15 seconds, it will cancel DRL operation and turn on the headlamps at 100 percent intensity. A path to ground is provided to the coil of the HLP relay. With a direct path to ground provided to the headlamps though the DRL control module, the headlamps will light at 100 percent intensity.
High Beam System Operation
The high-beam headlamp operation is controlled using the turn signal/headlamp switch lever on the steering column. In order to change headlamp operation from low-beam to high-beam, push the switch lever toward the instrument panel (until the detent is felt) and release. With the switch lever in the high beam position, ground is provided to the DRL control module through the turn signal/headlamp switch and splice pack 200 to G200. The DRL control module provides a ground to the coil of the dimmer relay. Since voltage is being applied to the dimmer relay coil, it becomes energized. Voltage is then applied through the closed contacts of the dimmer relay and the to the high beam lamps in the headlamps. Since ground is provided to the headlamps through the closed contacts of the energized DIM relay, the high beam lamps light. The high-beam indicator (blue) in the instrument cluster will light during high-beam headlamp operation. In order to change headlamp operation back to low-beam operation, pull the turn signal switch lever toward the driver (until the detent is felt) and release.Your best bet , take it to a qualified repair shop.

  1. Release the old blade. Lift the wiper arm off the window.
  2. Remove the wiper. Once rotated, the wiper will release from the wiper arm with a gentle click.
  3. Position the new blade. Place the small bar attachment on the new wiper blade into the hook on the wiper arm.
  4. Lock the blade into place. ...
  5. Done!

Sounds like an ignition module problem, with the connector (broken solder joint in the module or pin problem) or a malfunctioning device inside the module. I would try a new/rebuilt module.

Could be the accelerator cable is stuck or broken with the throttle full open, and when the engine hits over-rev it shuts down.

Oil on top of the plug (not in the cylinder) would be the spark plug tube grommets are bad. I would recommend changing them with the valve cover gasket.

The following instructions will allow you to reset any GM (General Motors), Cadillac, Oldsmobile, Buick, Pontiac theft lock radio.

Requirements: the theft lock radio must be in "LOC" mode.

1. Turn the ignition ON (The radio should display "LOC")
2. Hold down the Radio Presets 2 and 3 buttons for six seconds
3. The radio display changes from LOC to a three-digit number. Write this number down. You now have fifteen seconds to complete the next step.
4. Press the AM/FM button
5. The radio display changes to another three-digit number. Write this number to the right of the first one.
6. You now have a six-digit number, the first three digits are from STEP 03 and the last three digits are form STEP 05
7. Call 1-800-537-5140
8. Press 1 then # (pound). You'll hear "Invalid Code, try again"
9. Press 139010 or 106010 or 206010 or 202107 then # (pound). You will be asked to enter your four or six digit code followed by *
10. Enter the number from STEP 6 then *
11. Listen to the four-digit number and write it down. It will be repeated twice
12. Turn the ignition ON (The radio displays LOC)
13. Use the MN and HR buttons to enter the code from STEP 11
14. Press the AM/FM button. The radio display changes to "SEC". Your radio is now "un-locked" and usable.

If you fail to enter the correct code eight times, the radio goes into INOP mode. You have to wait an hour with the ignition on before the radio returns to LOC mode.

Hope this helps; keep in touch.

Don't change fuses unless blown. Usually, in the G8, the aux power F14 20 amp fuse blows before either the F22 or the F13. I bet that's what is blown in yours--it's usually what blows in mine.
