Here's a general guide. Specific steps might vary slightly depending on the exact engine (LT1 or LS1). Consult a repair manual specific to your 1996 Pontiac Trans Am's engine for precise instructions and diagrams. Repair manuals from Haynes or Chilton are good options.
Tools you'll likely need:
* Socket wrench set (metric)
* Screwdrivers (Phillips and possibly flathead)
* Possibly a ratchet and extensions
* New ignition control module (ensure it's the correct one for your vehicle)
* Wire brush (optional, for cleaning connections)
* Electrical grease (optional, for protecting connections)
* Shop rags
General Steps:
1. Locate the ICM: The ICM is usually mounted on the distributor (for LT1 engines) or near the distributor (for LS1 engines, sometimes on the intake manifold). Consult your repair manual for the exact location.
2. Disconnect the wiring harness: Carefully unplug the electrical connector from the ICM. Take note of how it's connected for reassembly. You might need to gently push the locking tab to release the connector.
3. Remove the ICM mounting hardware: This may involve removing screws or bolts depending on the mounting method.
4. Remove the old ICM: Gently pull the old ICM from its mounting location.
5. Clean the contacts: Use a wire brush to carefully clean the contacts on both the ICM and the wiring harness connector to ensure a good electrical connection.
6. Install the new ICM: Carefully align the new ICM with its mounting location and secure it with the mounting hardware.
7. Reconnect the wiring harness: Plug the connector back onto the new ICM, ensuring it's securely seated.
8. Reconnect the negative battery cable: Carefully reconnect the negative battery cable.
9. Test the vehicle: Start the engine and check for proper operation. If the problem persists, you might need to check other components in the ignition system.
Important Considerations:
* Engine type: The location and removal process might differ slightly depending on whether you have an LT1 or LS1 engine. Consult a repair manual specific to your engine.
* Diagram: A wiring diagram is highly recommended to avoid misconnecting wires. Your repair manual will have this.
* Safety: Always disconnect the negative battery cable before working on any electrical components to prevent electrical shocks.
* Professional help: If you're uncomfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic.
