Is Your GM Running Rough? Get Back on the Road with Confidence.
If your trusty 1997 Buick, Pontiac, or Chevrolet is suffering from frustrating issues like intermittent stalling, a persistent check engine light, poor fuel economy, or erratic transmission shifting, a failing Powertrain Control Module (PCM) is often the culprit. The PCM is the brain of your vehicle’s engine and transmission, and when it falters, it can cause a cascade of problems that are difficult to diagnose. This isn’t just an inconvenience; it’s a matter of reliability. You deserve a car that starts every time and gets you where you need to go without worry.
Common Symptoms & Your Direct-Fit Solution
A faulty engine computer can make your vehicle feel unpredictable. You might be experiencing one or more of the following signs:
- Check Engine Light: Often with codes related to internal module failure (e.g., P0601, P0605).
- No-Start or Hard-Start: The engine cranks but refuses to start, or only starts after many attempts.
- Stalling: The engine randomly shuts off while driving or idling at a stoplight.
- Poor Performance: Noticeable loss of power, hesitation during acceleration, and decreased fuel mileage.
- Erratic Shifting: The automatic transmission may shift harshly, at the wrong times, or not at all.

An Expert’s Note: We once had a customer with a ’97 Bonneville who had replaced multiple sensors trying to fix a persistent stalling problem that no shop could pinpoint. The car would run fine for days, then suddenly die at a stop sign. After installing one of our VIN-programmed PCMs, the problem was solved instantly. For these GM vehicles, a correctly programmed 1997 Buick LeSabre PCM 16218070 is often the simple, overlooked fix for the most complex-seeming issues.
Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming before the unit ships. It will arrive ready to be installed, flashed with the latest GM updates for the VIN you provide.
Is this a simple plug-and-play installation?
For most vehicles on the fitment list, the installation is straightforward. However, some GM vehicles of this era may require a simple “Security Relearn” or “CASE Relearn” procedure after installation, which can typically be done without special tools. Instructions for these procedures are widely available online or in service manuals.
Where do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, you will need to send us your 17-digit VIN. We cannot program and ship your part without it. Please double-check it for accuracy to ensure a perfect match.
How do I know for sure that my old PCM is bad?
While the symptoms listed are strong indicators, it’s always best to have a qualified mechanic perform a full diagnostic. Common confirmation steps include checking for specific diagnostic trouble codes (DTCs) like P0601-P0606, and verifying power and ground signals to the computer.
Will this fix my failed emissions test?
In many cases, yes. A faulty PCM can cause incorrect air/fuel mixtures and other issues that lead to failed emissions tests. A new, properly functioning 1997 Buick LeSabre PCM 16218070 restores the correct parameters and can resolve these problems.
