Restore Peak Performance to Your Vehicle
Is your Buick Lucerne, or another compatible GM vehicle, suffering from erratic behavior? A faulty Engine Control Module (ECM) is often the culprit behind a host of frustrating issues, from poor fuel economy and rough idling to a no-start condition. This direct-fit Engine Control Module, part number 19210737, is the definitive solution to get your vehicle back on the road and running as it should. The ECM is the central computer of your engine, meticulously managing fuel injection, ignition timing, and emissions systems. When it fails, the entire powertrain’s performance is compromised.
From the Diagnostic Bay
We had a 2008 Chevy Impala come in with a persistent P0300 random misfire code. The owner had already replaced all the spark plugs, wires, and even the ignition coil pack with no success. The engine would stumble under load and the check engine light was a constant annoyance. After hooking up our diagnostic scanner and monitoring live data, we noticed the fuel trim values were completely out of spec and unresponsive. This pointed away from the ignition system and towards the computer itself. We installed a VIN-programmed ECM just like this one, performed the security relearn, and the car ran perfectly. It’s a classic case where chasing parts gets expensive; sometimes, the problem lies with the brain, not the body.
Is Your ECM Failing? Common Symptoms
A failing engine computer can manifest in various ways, often mimicking other component failures. If you’re experiencing any of the following, it might be time to inspect your ECM:
- ✔ Check Engine Light: The most obvious sign, often with codes related to sensors, misfires, or internal processor faults.
- ✔ Engine Stalling or Misfiring: The engine may cut out unexpectedly while driving or run rough due to incorrect fuel and spark commands.
- ✔ Poor Performance & Fuel Economy: A compromised ECM can’t efficiently manage the engine, leading to a noticeable drop in power and more trips to the gas station.
- ✔ No-Start Condition: The vehicle cranks but won’t start because the ECM isn’t activating the fuel pump or ignition system.
- ✔ Inconsistent Shifting: The ECM works with the transmission control module, and a fault can lead to harsh or erratic gear changes.
- ✔ Communication Errors: Your mechanic’s scan tool may be unable to communicate with the vehicle’s computer system.

Yes, it is shipped programmed to your specific VIN. In most cases, you will only need to perform a standard security relearn procedure after installation, which pairs the new module to your vehicle’s keys and anti-theft system. Instructions for this are widely available online or in service manuals.
What information do you need from me?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN) to program the module correctly. Please provide this information after your purchase to ensure a speedy delivery.
Where can I find my VIN?
Your VIN can be found on a metal plate on the driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, and on your vehicle’s registration and insurance documents.
Will this fit vehicles other than a 2006 Buick Lucerne?
Absolutely. This ECM is compatible with a vast range of GM vehicles. Please check the detailed fitment list provided in the description to confirm it matches your specific make, model, year, and engine size.
