Are you tired of dealing with a persistent check engine light, erratic engine performance, or a car that just won’t start? A failing Powertrain Control Module (PCM) is a common cause of these frustrating issues, leaving you stranded and stressed. This professionally programmed PCM is the definitive, hassle-free solution to restore your vehicle’s performance and get you back on the road with confidence.
We take the guesswork out of the repair by flashing this module with the latest GM software updates, specifically calibrated to your vehicle’s unique Vehicle Identification Number (VIN). This ensures a seamless installation and proper communication with all of your vehicle’s systems, something a generic, off-the-shelf unit simply can’t guarantee. By installing our precisely programmed 1998 Buick Skylark PCM, you’re not just replacing a part; you’re restoring your vehicle’s operational integrity.

- Noticeable decrease in fuel economy
- Poor acceleration or hesitation

Frequently Asked Questions
Do I need to do any programming myself?
No. This 1998 Buick Skylark PCM arrives fully programmed to your vehicle’s VIN and is ready for installation right out of the box. It’s a true plug-and-drive solution.
Where do I provide my vehicle’s VIN?
After you complete your purchase, you can add your VIN to the ‘notes’ section of your order. If you forget, we will contact you to get the necessary information before programming and shipping the unit.
Will this work with my vehicle’s anti-theft system?
In many cases, yes. However, some GM vehicles of this era may require a simple ‘Security Relearn Procedure’ after installation to sync the new PCM with the anti-theft system. This procedure can typically be performed by the owner in about 15-30 minutes and does not require special tools.
How can I be sure this is the correct part for my car?
The best way to ensure compatibility is to match one of the service numbers listed (e.g., 09356741, 16236757) to the number on your current module. You can also confirm your vehicle’s make, model, and year are on our fitment list.
What does ‘flashed with the newest updates’ actually mean?
It means we load the module with the most recent and stable software version released by GM for your specific vehicle. This often includes fixes for common bugs, improved transmission shift points, and better fuel management that were not available when your car was new.
What is the warranty on this part?
This unit is backed by our one-year replacement warranty, giving you confidence in your repair.
