Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will provide clear instructions on how to do this. We cannot ship your part until we receive the VIN, as the programming is specific to your vehicle.
Is this a difficult part to install myself?
For someone with basic mechanical skills, replacing a PCM is typically straightforward. It usually involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and then installing the new one in the reverse order. Always consult a repair manual for your specific vehicle’s procedure.
Will I need to do anything after installation?
In many cases, no further action is needed. However, some GM vehicles of this era may require a Crankshaft Position System Variation (CASE) relearn procedure to avoid a check engine light. This can be done with a capable scan tool and is a standard procedure for many shops.
Is this compatible with my 1998 Pontiac Grand Prix?
Yes, this PCM is compatible with a wide range of 1998 and 1999 GM vehicles that use the service numbers listed in the description, including the Grand Prix, Buick Century, Oldsmobile Intrigue, and many others. The key is matching the service number and providing your VIN for correct programming.
What if my original part number isn’t listed?
The service numbers provided (e.g., 09356741, 16236757, 9366314) cover many original part numbers. If you are unsure about compatibility, please contact us with your VIN and original part number before ordering, and our experts will be happy to verify the correct fitment for you.
