Is Your 1998 Firebird Running Rough, Stalling, or Throwing Confusing Codes?
If you’re dealing with frustrating drivability issues in your 1998 Pontiac Firebird, the problem often points directly to a failing Powertrain Control Module (PCM). As a technician with over 20 years of experience, I’ve seen how a faulty PCM can turn a reliable car into a source of constant headaches. It’s the brain of your vehicle, controlling everything from fuel mixture and ignition timing to transmission shift points. When it starts to fail, the symptoms can be unpredictable and difficult to diagnose.

From the Shop Floor: “A customer’s ’98 Camaro with the 3.8L engine—which uses this exact same PCM—came in last week with a persistent P0601 (Internal Control Module Memory Check Sum Error) and intermittent stalling at red lights. He’d already replaced sensors trying to chase the problem. We confirmed the PCM was the culprit. I sent him one of our pre-programmed units, he installed it in his driveway in about 20 minutes, and the car has been running perfectly ever since. Getting the programming right from the start is the key.”
Easy Installation for Your 1998 Firebird PCM
You don’t need to be a master mechanic to replace your PCM. With a few basic hand tools, you can get your Firebird back to factory-spec operation. Follow these simple steps:
- Safety First: Always disconnect the negative terminal from your car’s battery before starting any electrical work.
- Locate the PCM: On the 1998 Firebird, the PCM is typically located in the engine compartment on the passenger side, near the firewall.
- Disconnect Connectors: Carefully unclip the wiring harness connectors from the old module. Inspect the pins and connectors for any corrosion or damage.
- Remove the Old Module: Unbolt the PCM from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount your new, pre-programmed PCM onto the bracket and securely reconnect the wiring harnesses. You should hear a ‘click’ as they lock into place.
- Reconnect Battery: Re-attach the negative battery terminal. The vehicle may need to go through a brief idle relearn procedure, which typically involves starting the car and letting it idle for a few minutes.
