Is Your GM Vehicle Running Rough? Get Back on the Road with Confidence.
There’s nothing more frustrating than a car that won’t run right. If your late-90s GM vehicle is suffering from a persistent Check Engine Light, unpredictable stalling, poor fuel economy, or erratic shifting, the problem often points directly to a failing Powertrain Control Module (PCM). This isn’t just an inconvenience; it’s an issue that affects your vehicle’s reliability and your peace of mind. This pre-programmed engine computer is the definitive solution to restore your car’s original performance and dependability.

Expert Insight: The Heart of Your Vehicle
Think of the PCM as the brain of your engine and transmission. In these classic 1990s GM vehicles, the original modules have endured over two decades of intense heat cycles and vibrations. Over time, internal components like capacitors can degrade, and solder joints can develop micro-fractures. This leads to the intermittent and confusing problems you might be facing. Simply replacing a faulty module with a generic, unprogrammed unit won’t work. Our process of programming a quality replacement like this 1998 Firebird PCM 9357034 to your specific VIN is the most effective way to ensure all vehicle systems communicate correctly, restoring the crisp performance your car had when it was new.
Don’t let a failing computer keep your car off the road. This is the most reliable and efficient way to restore your vehicle’s core functions. By providing us with your VIN at checkout, you ensure that the 1998 Firebird PCM 9357034 you receive is a true plug-and-play solution, tailored specifically for your car.
Frequently Asked Questions
What exactly does the PCM do?
The Powertrain Control Module (PCM), also known as the Engine Control Unit (ECU), is your vehicle’s central computer. It controls critical functions like fuel injection, ignition timing, transmission shifting, and emissions systems to ensure optimal performance and efficiency.
How do I provide my vehicle’s VIN?
You can provide your 17-digit Vehicle Identification Number (VIN) in the notes section during checkout or reply to your order confirmation email. We cannot ship your part until we receive the VIN, as programming is a required step.
Will I need to do anything after installing this PCM?
In most cases, this is a plug-and-play installation. However, some GM vehicles may require a simple security relearn procedure (also known as a CASE relearn) to sync the new PCM with your vehicle’s anti-theft system. This procedure can typically be done without special tools and instructions are widely available online.
Is this a direct replacement for my original part?
Yes. This module is a direct replacement for the service numbers listed in the description, including 09356741, 16236757, 9357034, and others. Please verify your original part number or contact us if you are unsure about compatibility.
What does “pre-programmed” mean for me?
“Pre-programmed” means we load your vehicle’s specific software onto the module using your VIN before we ship it. This ensures the computer works perfectly with your car’s engine, transmission, and options, eliminating the need for a costly programming service at a dealership.
