Restore Peak Performance and Reliability to Your GM Vehicle
If you’re dealing with frustrating and unpredictable issues like engine stalling, a no-start condition, erratic transmission shifting, or a persistent Check Engine Light, the culprit is often a failing Powertrain Control Module (PCM). As the central computer for your engine and transmission, a faulty PCM can wreak havoc on your vehicle’s drivability and fuel economy. This isn’t just an inconvenience; it’s a critical failure that needs a reliable solution. This replacement PCM, part number 9357034, is the definitive fix for your 1998 Camaro and a wide range of other GM vehicles.
Case Study: The Phantom Stall
A customer brought in his ’98 Firebird 3.8L, a sister car to the Camaro, with an issue that had stumped two other shops. It would run perfectly for days, then suddenly die at a stoplight and refuse to restart for an hour. There were no consistent codes, just a history of random misfires. After checking fuel pressure and ignition systems, which were all fine, I focused on the brain. On these older GM platforms, I’ve seen internal PCM solder joints and capacitors fail from years of heat cycles. We connected a lab scope and saw the 5-volt reference signal drop out intermittently. The solution was a reliable, properly programmed PCM. This isn’t just a part; it’s the restoration of your car’s core logic.
Is Your Vehicle Showing These Signs of PCM Failure?
A failing engine computer can manifest in numerous ways. If you’re experiencing any of the following, a new PCM is the most likely solution:
- âś” Check Engine Light is on with codes pointing to internal module failure (e.g., P0601, P0602, P0605).
- âś” Your vehicle won’t start, or it starts and immediately stalls.
- âś” Noticeable decrease in fuel efficiency for no apparent reason.
- âś” Harsh or erratic automatic transmission shifting.
- âś” The engine misfires, hesitates, or runs rough.
- âś” Failure to pass an emissions/smog test.
The Smart Solution: A VIN-Programmed 1998 Camaro PCM

Simply provide your vehicle’s 17-digit VIN during checkout, and our technicians will flash this module with the latest, most stable GM-certified software specific to your car. This ensures perfect compatibility with your engine, transmission, and all factory options. It’s a true plug-and-play solution designed to get you back on the road with confidence.
A Straightforward Guide to Installation
Installing your new PCM is a manageable job for a DIYer with basic tools. Follow these steps carefully.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the PCM: On most of these vehicles, the PCM is located in the engine bay, often near the air filter housing or on the passenger-side fender.
- Disconnect Connectors: Carefully unclip the wiring harness connectors from the old PCM. They have locking tabs that may need to be gently pried up. Avoid pulling on the wires themselves.
- Remove the Old Module: Unbolt the old PCM from its mounting bracket.
- Install the New PCM: Mount your new, pre-programmed PCM and securely plug in the wiring harnesses. You should hear a ‘click’ as they lock into place.
- Reconnect Battery: Re-attach the negative battery terminal.
- Perform Security Relearn: You will need to perform a simple key-cycle security relearn procedure. Turn the key to ‘ON’ for 10-15 minutes, then ‘OFF’ for 10 seconds. Repeat this 3 times. On the fourth try, the vehicle should start.

Frequently Asked Questions
How do I provide my VIN?
After you complete your purchase, you will receive an email with instructions on where to send your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it.
Is this part truly plug-and-play?
Yes. Because we program it to your specific VIN, it will be ready to install right out of the box. The only additional step is a simple security relearn procedure that you can do yourself in about 30 minutes with just your car key.
Will this fix my car’s specific problem?
This PCM is a direct solution for failures of the module itself. While it resolves the vast majority of electronic drivability issues, we always recommend proper diagnostics to rule out other problems like faulty sensors or wiring before ordering.
What does ‘flashed with the newest updates’ mean?
Manufacturers like GM often release software updates for their vehicles to fix bugs, improve transmission shifting, or enhance engine performance. We ensure your replacement PCM is loaded with the very latest software available for your VIN, giving you a better-than-original solution.
Do I need to send my old PCM back?
No core charge or return is required for this part. You can keep or recycle your old module.
