Restore Peak Performance to Your 1997 Oldsmobile Cutlass or Chevrolet Malibu
Is your trusty 1997 Cutlass or Malibu suddenly acting up? If you’re dealing with frustrating issues like a persistent check engine light, poor fuel mileage, stalling, or a no-start condition, the root cause is often a failing Engine Control Module (ECM). As the central computer of your vehicle, the ECM is responsible for managing everything from fuel injection and ignition timing to transmission shifting. When it falters, the entire vehicle’s performance suffers. This replacement ECM, part number 16247321, is the definitive solution to bring your vehicle back to its reliable, factory-spec operation.
We take the guesswork and hassle out of the replacement process. Unlike a generic unit from a salvage yard, this ECM is meticulously programmed to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This critical step ensures complete compatibility with your engine, transmission, and factory options. We load the latest GM-authorized software updates, which can correct common drivability issues and improve overall efficiency. This isn’t just a replacement part; it’s a restoration of your vehicle’s electronic nervous system.
From the Diagnostic Bay
A few months back, a 1997 Chevy Malibu with the 3.1L V6 was towed in. The owner had spent a small fortune replacing the spark plugs, wires, ignition coils, and even the fuel pump, trying to solve an intermittent stalling and hard-start problem. The check engine light would come and go, throwing codes that pointed in different directions each time. After confirming fuel pressure and spark were good, we hooked up our professional scan tool. We noticed the data stream from the ECM was erratic—injector pulse width was jumping all over the place for no reason. We connected a test ECM, and the engine immediately smoothed out and ran perfectly. The original ECM had internal circuit failure, causing it to send incorrect signals. We installed a VIN-programmed unit just like this one, performed the quick security relearn, and the car ran like it just left the showroom. It’s a classic case of symptoms pointing everywhere, but the true culprit being the vehicle’s central computer.

Frequently Asked Questions
Do I need to have this ECM programmed?
No. The main benefit of our service is that we handle all the programming for you before shipment. Simply provide your vehicle’s VIN when you place your order, and the module will arrive ready for installation, loaded with the correct software for your car.
Is this a difficult part to install?
The physical installation is straightforward for someone with basic mechanical skills. It typically involves disconnecting the battery, unplugging the electrical connectors from the old ECM, unbolting it, and then installing the new one in reverse order. After installation, you may need to perform a simple security relearn procedure, which can usually be done without any special tools. Instructions for this procedure are widely available online or in service manuals.
Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found in several locations: on a metal plate on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, and on your vehicle’s registration and insurance documents.
Will this computer fix my check engine light?
If the check engine light is caused by a faulty ECM, then yes, this part is the correct solution. However, the check engine light can be triggered by many other components (like a bad oxygen sensor or a loose gas cap). It is always recommended to have the trouble codes read by a scanner to help diagnose the issue before ordering parts.
What happens if I forget to provide my VIN?
Providing your VIN is a required step for this purchase. We cannot program or ship the ECM without it. The programming is essential for the part to function in your vehicle. Our team will contact you after your purchase to remind you if the VIN was not included with the order, which may delay shipment.
