Is Your Firebird Running Rough? Get Back on the Road with Confidence.
There’s nothing more frustrating than when your 1998 Pontiac Firebird isn’t performing as it should. Whether you’re dealing with a persistent Check Engine Light, unpredictable stalling, or rough gear changes, a faulty Powertrain Control Module (PCM) is often the culprit. This isn’t just a part; it’s the central computer of your vehicle, and when it fails, it can bring your driving enjoyment to a halt. We provide the definitive, pre-programmed solution to restore your car’s performance and reliability, getting you back to enjoying the drive.
Common Symptoms & Your Direct-Fit Solution
A failing engine computer can manifest in numerous ways. If you’re experiencing any of the following, our professionally programmed PCM is the answer:

- Poor or erratic automatic transmission shifting

- Engine stalling or cutting out unexpectedly
- Vehicle won’t start, despite a good battery and starter

An Expert’s Note on VIN Programming
As a technician with over two decades of experience, I can’t overstate the importance of proper VIN programming for these vehicles. In the late ’90s, GM’s Vehicle Anti-Theft System (VATS) became deeply integrated into the PCM. Simply swapping in a used module from another car will almost always result in a no-start condition because the VATS key code won’t match. Our process of flashing your specific VIN not only loads the correct engine and transmission files but also ensures the security system recognizes the new module, saving you from a massive headache and additional diagnostic costs. This is the correct way to replace a 1998 Firebird PCM 9357440.
Don’t let a faulty computer keep your classic off the road. This is the most reliable and straightforward way to solve your PCM-related issues and get your car running strong again. After purchase, simply provide us with your VIN, and we’ll handle the complex programming for you. Your expertly prepared 1998 Firebird PCM 9357440 will be shipped directly to your door, ready for installation.
Frequently Asked Questions
Do I need to do any programming myself?
No. This PCM comes fully programmed to the VIN you provide. The service is designed to be plug-and-play. In some GM vehicles, a simple security relearn procedure may be required, which takes about 30 minutes and can be done without any special tools. We include instructions for this common procedure.
Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, your insurance card, or on the driver’s side of the dashboard, visible through the windshield.
Will this fix my check engine light?
If the check engine light is caused by an internal fault in your old PCM (like a P0601 code), this unit is the correct fix. However, a check engine light can be caused by many other components. We always recommend having the codes professionally scanned to confirm the PCM is the point of failure before ordering.
Is this part difficult to replace?
On most compatible models, including the 1998 Firebird, the PCM is located in a reasonably accessible area, often under the hood or behind the glove box. Replacement typically involves disconnecting the battery, unplugging a few electrical connectors, and removing a few bolts. It is a task many DIY mechanics can handle with basic tools.
What happens after I place my order?
After you complete your purchase, you will need to send us your vehicle’s VIN. Once we receive your VIN, our technicians will program the module with the latest GM software specific to your car. The unit is then tested and shipped out to you.
Is this a new or used part?
This is a high-quality, inspected, and tested OEM replacement part that has been professionally programmed for your specific vehicle application.
