Question about 2002 Oldsmobile Bravada
The warning light is telling the driver the computer has a problem with a sensor or component that could affect performance and emissions.
You need to get the computer scanned for trouble codes to proceed with troubleshooting.

There are over 2000 different trouble codes that can store with your check engine light. Probably 30-50 of them (or sequences of them) can trigger limp-mode or safe-drive mode on most vehicles. In your case, I would strongly suspect a problem with the electronic throttle control assembly. For safety, vehicles with electronic throttle frequently limit speed and rpm to very low numbers when a fault is detected to prevent runaway accelerations and high speed collisions. Have it checked by a professional. It may be as simple as a sensor on your accelerator pedal, or the throttle assembly itself could be starting to fail. In either case, it shouldnt be played with unless you have the proper diagnostic equipment (a Tech-2 Scantool) and good repair data.
NOTE: Clearing the code with a generic tool or disconnecting the battery MAY allow the car to reset, and if the problem is intermittant, it may become normally drivable till the next time thr problem occurs. HOWEVER...the technician who fixes the car really should have access to the original failure information stored in the freezeframe snapshot the computer took when it set the code. If you reset the light or disconnect the battery, that info will be erased and make make diagnosis and repair much much more difficult.

replace outside temp, sensor and check your refrigerant for recommended pressure, your outside air temperature sensor is located infront of your car, upper/ insidegrille

I would replace number 6 injector or have it reconditioned.There is dirt in the nozzle of the injector that causes this problem.No injector cleaner will clean dirt rust from the fuel tank, if that has entered them.
