Restore Peak Performance to Your GM Vehicle
If you’re dealing with a frustrating Check Engine Light, erratic engine behavior, or a no-start condition in your 1998 Oldsmobile Intrigue or other compatible GM model, a failing Powertrain Control Module (PCM) is often the culprit. As the brain of your vehicle’s engine and transmission, its proper function is critical. This replacement PCM, part number 9357034, is the reliable, direct-fit solution you need to get your car running smoothly again. Forget expensive dealership visits and programming fees. We flash this module with the latest GM software updates, specifically matched to your vehicle using your VIN. This ensures optimal performance, fuel economy, and emissions control right out of the box.
From the Diagnostic Bay: The Phantom No-Start
I once had a 1998 Pontiac Grand Prix in the shop that would randomly refuse to start. The owner had already replaced the battery and starter. All the basic checks were fine—fuel pressure was good, spark was present when it decided to run. The scanner, however, would intermittently lose communication with the PCM. After checking the power and ground circuits to the module, we found them to be solid. This pointed directly to an internal failure within the PCM itself, a common issue on these platforms where heat cycles and age cause internal solder joints to fail. Swapping in a pre-programmed PCM like this one had the car reliably starting every single time, solving a problem that had stumped others for weeks.
Is Your Vehicle Showing These Symptoms?
A failing computer can cause a wide range of issues. If you’re experiencing any of the following, it might be time to replace your PCM:
- ✔ Persistent Check Engine Light (CEL)
- ✔ Diagnostic Trouble Codes (DTCs) related to internal module failure, such as P0601, P0602, or P0606
- ✔ Engine stalling, stumbling, or misfiring
- ✔ Harsh or incorrect automatic transmission shifting
- ✔ Poor fuel mileage
- ✔ Failure to pass an emissions test
- ✔ Complete no-start condition where the engine cranks but won’t fire
A Straightforward Guide to Installation
Installing your new 1998 Intrigue Powertrain Control Module is a manageable job for a DIYer with basic tools. Just follow these steps carefully.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the PCM: On many of these vehicles, the PCM is located in the engine compartment, often inside the air filter housing or mounted to the firewall. Consult a repair manual for your specific model’s location.
- Disconnect Connectors: Carefully unclip the wiring harness connectors from the old PCM. These connectors have locking tabs that must be released before they can be pulled off. Do not force them.
- Remove the Old Module: Unbolt the old PCM from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount your new, pre-programmed PCM in the same location. Securely re-attach the wiring harness connectors, ensuring they click into place.
- Reconnect the Battery: Re-attach the negative battery terminal.
- Perform Security Relearn: Most GM vehicles of this era require a security relearn procedure to allow the vehicle to start. This typically involves turning the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’ for 10 seconds, and repeating this cycle three times. Your vehicle’s service manual will have the exact procedure.

Frequently Asked Questions
How does the VIN programming work?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. We use this number to access the official GM database and load the exact, most current software calibration for your specific vehicle onto the module before we ship it. This ensures it works perfectly upon installation.
Is this a plug-and-play part?
Almost. Because we pre-program it to your VIN, you will not need a dealer’s scan tool for software flashing. However, you will need to perform a simple security relearn procedure with your key, which takes about 30 minutes and requires no special tools. This syncs the new PCM with your vehicle’s anti-theft system.
Will this fix my specific problem?
This 1998 Intrigue Powertrain Control Module is the correct part to fix issues caused by a faulty PCM. While it solves many common problems like stalling, misfires, and certain error codes, it’s important to properly diagnose your vehicle first to ensure the PCM is the root cause.
What if I have a different part number on my old module?
This module replaces several service numbers, including 09356741, 16236757, 9357440, and others listed above. As long as your vehicle is on the compatibility list and your old part number is one of the listed interchanges, this module will work correctly.
Do I need to send my old PCM back?
No core charge or return is required for this particular module. You can keep or responsibly recycle your old part.
