Restore Peak Performance to Your GM Vehicle
Is your 1998 Chevrolet Camaro or another GM vehicle from that era suffering from perplexing issues like poor fuel economy, erratic shifting, a persistent check engine light, or even a no-start condition? The Powertrain Control Module (PCM), the electronic brain of your vehicle, is often the culprit. This vital component manages everything from fuel injection and ignition timing to transmission shift points and emissions controls. When it fails, the symptoms can be widespread and frustrating. This replacement PCM, part number 09356741, is the definitive solution to restore your vehicle’s factory performance and reliability.
From the Diagnostic Bay
We had a 1998 Firebird 3.8L come into the shop with a ghost of a problem. The owner complained of an intermittent stall at stoplights, but it would always restart. There were no consistent trouble codes, just a random misfire code that would pop up and disappear. We checked the fuel pressure, ignition system, and sensors—all tested fine. After hours of chasing wires, we decided to monitor the PCM’s data stream on a long test drive. We finally caught it: for a split second, the injector pulse width command would drop to zero, starving the engine of fuel. It was a classic case of a failing driver inside the PCM. Swapping in a correctly programmed module like this one solved the issue instantly, saving the customer from replacing dozens of perfectly good parts.
Common Symptoms of a Failing PCM
- ✔ Check Engine Light is illuminated with various, often inconsistent, trouble codes.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ The engine cranks but refuses to start (no-start condition).
- ✔ Failure to communicate with a diagnostic scan tool.
- ✔ Problems with emissions testing.

Frequently Asked Questions
How does the programming process work?
After you complete your purchase, you will need to provide us with your vehicle’s VIN. Our technicians use this number to load the exact GM factory software for your specific vehicle onto the module. This ensures it works correctly right out of the box.
Do I need to have this programmed by a dealer?
No. The main benefit of our service is that the module arrives at your door fully programmed and ready for installation. This saves you the time, hassle, and cost of a dealership visit.
Is this a simple part to install for a DIY mechanic?
Yes, for most models this is a straightforward installation. It typically involves disconnecting the battery, locating the old PCM (often in the engine bay or under the dash), unplugging the electrical connectors, unbolting the unit, and reversing the process with the new one. Always disconnect the battery’s negative terminal before starting.
Will this fix my specific problem?
This PCM will resolve issues directly caused by a faulty control module. While the symptoms listed are common indicators of PCM failure, we always recommend a proper diagnosis by a qualified mechanic to confirm the PCM is the root cause before ordering.
What is a VIN and where do I find it?
The VIN is your car’s unique 17-digit serial number. You can typically find it on a plate on the driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
