To reset the check engine light on a 1997 Oldsmobile Achieva, you can disconnect the negative battery cable for about 15 minutes to clear the engine control unit's memory. Alternatively, you can use an OBD-II scanner to reset the check engine light after addressing any underlying issues. It's important to ensure that any problems triggering the light are resolved before resetting it, as the light will likely come back on if the issue persists.

check the oil before you start you car, if its low on the stick and it in to add line add a quart of oil. And check to see if you have a puddle under the engine of the car. If you do open the hood a check the left side of the engine to see if there any oil drops on the ac comp top, if there is the timing gasget need to be replace.
