Restore Peak Performance to Your GM Vehicle
Is your 1998 Oldsmobile Intrigue or another late-90s GM vehicle suffering from frustrating, hard-to-diagnose issues? A failing Powertrain Control Module (PCM), the engine’s computer, is often the culprit behind problems that can leave even seasoned mechanics scratching their heads. This replacement PCM, part number 9356741, is the definitive solution to restore your vehicle’s reliability, drivability, and efficiency. We take the guesswork and hassle out of the repair by programming the module specifically to your vehicle’s VIN before it ships. This ensures it communicates perfectly with your car’s systems right out of the box.
Case Study: A Tricky Diagnosis
I remember a 1998 Buick LeSabre that came into my shop with a complaint of intermittent stalling at stoplights and a persistent Check Engine Light. The owner had already replaced the spark plugs, wires, and a couple of sensors with no luck. The scanner showed a P0601 code (Internal Control Module Memory Check Sum Error), a classic sign of internal PCM failure. We installed one of these VIN-programmed modules, performed the security relearn, and the car ran perfectly. It’s a reminder that sometimes the root cause is the computer itself, not just the parts it controls.
Is Your Vehicle Showing These Symptoms?
A failing PCM can manifest in numerous ways. If you’re experiencing any of the following, this module is likely the fix you need:
- ✔ Persistent Check Engine Light (CEL) with codes like P0601, P0602, or other communication errors.
- ✔ Unexplained engine stalling or shutting off while driving.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ A no-start condition where the engine cranks but won’t fire up.
- ✔ Noticeable decrease in fuel economy.
- ✔ Failure to pass an emissions test due to module-related faults.
The Advantage of VIN Programming
Don’t waste time and money at a dealership for programming. When you purchase from us, you get a 1998 Intrigue Powertrain Control Module that is ready for installation. Simply provide us with your vehicle’s 17-digit VIN during checkout. Our technicians will flash the module with the latest GM-certified software updates specific to your car. This critical step ensures all components, from the engine and transmission to the anti-theft system, function exactly as the manufacturer intended.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery and secure it away from the post to prevent accidental contact.
- ✔ Locate the PCM: On most of these vehicles, the PCM is located in the engine bay, often inside the air filter housing or mounted to the firewall. Consult a repair manual for your specific model if you’re unsure.
- ✔ Disconnect Connectors: Carefully unlatch and remove the electrical wiring harnesses from the old module. Inspect the connectors for any corrosion or damage.
- ✔ Remove the Old Module: Unbolt the old PCM from its mounting bracket.
- ✔ Install the New Module: Bolt your new, pre-programmed PCM into place.
- ✔ Reconnect Everything: Firmly re-seat the electrical connectors until they click into place. Reconnect the negative battery terminal.
- ✔ Perform Security Relearn (If Necessary): Many GM vehicles of this era require a simple key-cycle procedure to sync the new PCM with the security system. Typically, this involves turning the key to ‘ON’ for 10-15 minutes, then ‘OFF’ for 10 seconds, and repeating this two more times.

Frequently Asked Questions
Do I need to do anything after installing this PCM?
In many cases, you may need to perform a simple security relearn procedure, also known as a VATS relearn. This typically involves a 30-minute key cycle process that can be done in your driveway without any special tools. Instructions are widely available online for your specific vehicle.
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 cannot ship your module until we receive this information, as the programming is essential for it to function.
Will this fix my car’s specific problem?
This 1998 Intrigue Powertrain Control Module is a direct solution for failures within the computer itself. While it resolves many common issues like stalling and no-starts, it’s always best to ensure your vehicle’s other components (sensors, wiring, fuel system) are in good working order. A proper diagnosis is key.
Is this a new or used part?
This is a high-quality, tested replacement part that has been verified to meet or exceed original equipment specifications. It is loaded with fresh, VIN-matched software from GM.
What if I have a different service number on my original part?
This module is a direct replacement for several service numbers, including 09356741, 16236757, 9357034, 9357440, and 9366314. As long as your vehicle is on the compatibility list, this module will function correctly once programmed to your VIN.
