Restore Peak Performance to Your Vehicle
Is your Pontiac Grand Am, Chevy S10, or other compatible GM vehicle suffering from erratic engine behavior, poor fuel economy, or a persistent Check Engine Light? The Powertrain Control Module (PCM), the electronic brain of your vehicle, is often the culprit. This replacement PCM, part number 8162280160, is the definitive solution to restore your engine’s reliability and efficiency. It arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN), ensuring a seamless, plug-and-play installation process.
Symptoms of a Failing PCM
- ✔ Check Engine Light: The most common indicator, often with codes pointing to multiple, unrelated sensor failures.
- ✔ No-Start or Hard-Starting: The engine cranks but refuses to start, or takes an unusually long time to fire up, especially when warm.
- ✔ Poor Engine Performance: Noticeable loss of power, hesitation during acceleration, and rough idling.
- ✔ Reduced Fuel Economy: A sudden and unexplained drop in your vehicle’s MPG can signal an inefficiently operating engine controlled by a faulty PCM.
- ✔ Erratic Shifting: The PCM also influences transmission behavior. A bad module can cause harsh shifts, delayed engagement, or getting stuck in one gear.
- ✔ Stalling: The engine may stall intermittently for no apparent reason, both at idle and while driving.
From the Diagnostic Bay
We had a 1998 Chevy S10 with the 2.2L engine come into the shop that was giving the owner fits. It would randomly stall at stoplights and had a check engine light with codes for the oxygen sensor, MAP sensor, and a transmission solenoid. The owner had already replaced all three parts with no change. After confirming the wiring to the sensors was intact, we suspected the PCM. The internal drivers responsible for processing those signals were failing, creating false codes. We installed a VIN-programmed PCM, performed the security relearn, and the truck ran perfectly. It’s a classic case where the PCM is the root cause of what looks like multiple separate problems.
Why Choose Our 1997-1999 Grand Am PCM?
Your vehicle’s engine and transmission rely on precise data to function correctly. A generic, non-programmed module from a salvage yard can cause more problems than it solves, leading to compatibility issues, persistent warning lights, and even a no-start condition. Our process eliminates this guesswork. We take your VIN and flash the module with the latest, most stable software updates from GM. This ensures that the PCM is perfectly matched to your vehicle’s factory specifications, including engine size, transmission type, and emissions equipment. This professional programming is essential for a successful and lasting repair, making our 1997-1999 Grand Am PCM the most reliable choice for your vehicle.
Simple Installation Process
Once you receive your pre-programmed module, the physical installation is straightforward. First, disconnect the negative battery terminal. Locate your existing PCM (locations vary by model, see fitment list below), disconnect the electrical connectors, and unbolt the unit. Install the new module in its place, reconnect the connectors, and finally, reconnect the battery. While the module is programmed for your engine and transmission, many GM vehicles of this era require a simple security relearn procedure (often called a Passlock or VATS relearn) to allow the vehicle to start. This procedure can typically be done in your driveway without special tools and involves a sequence of turning the key on and off. Instructions are readily available online for your specific model.

Frequently Asked Questions
Do I need to send you my old PCM?
No core charge or return is required for this part. You can keep your old module.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We must have your VIN to program the module before we can ship it.
Is this part difficult to install?
The physical replacement is typically very simple, requiring only basic hand tools to disconnect the battery and unbolt the old module. The most critical step after installation is performing the security relearn procedure, which is required for the vehicle to start. This procedure does not require special scan tools.
Will this fix my specific problem?
This PCM is a direct solution for vehicles experiencing failures related to the engine computer. If your vehicle displays multiple symptoms like a check engine light with various codes, stalling, and poor performance, a faulty PCM is a very likely cause. However, we always recommend a proper diagnosis by a qualified mechanic to rule out other issues like bad wiring or sensors.
What does “programmed with the newest updates” mean?
Over the life of a vehicle, manufacturers often release software updates to fix bugs, improve transmission shifting, or enhance engine efficiency. We ensure your replacement PCM is loaded with the very latest GM software available for your specific VIN, giving you a module that is often better than the one that originally came in your car.
