Where is the ECM on 84 olds cutlass?

The Engine Control Module (ECM) on an 1984 Oldsmobile Cutlass is typically located under the dashboard on the driver's side, near the steering column or behind the glove compartment. You may need to remove some panels or the glove box to access it. It's a rectangular metal or plastic box with connectors plugged into it. Always ensure the vehicle is turned off and the battery is disconnected before attempting any work on the ECM.
