Is Your Alero or Grand Am Running Rough? We Have the Solution.
Dealing with frustrating engine problems like stalling, poor fuel mileage, or a persistent check engine light can make driving your car a stressful experience. If your 1999 Oldsmobile Alero or Pontiac Grand Am is suffering from these issues, a failing Engine Control Module (ECM) is often the culprit. This isn’t just an inconvenience; it affects your car’s performance, reliability, and fuel efficiency. We offer the definitive, hassle-free solution: a professionally programmed 1999 Alero Grand Am ECM 09361733, ready to restore your vehicle’s original performance and get you back on the road with confidence.
Common Symptoms & Your Solution
A faulty ECM can cause a wide range of confusing and intermittent issues. You might be experiencing one or more of the following:
- Check Engine Light: The light is on with codes like P0601, P0602, P0605, or other communication-related faults.
- Engine Stalling: The engine cuts out unexpectedly, either while driving or at idle.
- No-Start Condition: The engine cranks but refuses to start.
- Poor Performance: You may notice a significant loss of power, hesitation during acceleration, or rough idling.
- Reduced Fuel Economy: Your car is suddenly using more gas than usual.
- Erratic Shifting: The automatic transmission may shift harshly or at the wrong times.

An Expert’s Note on VIN Programming
“For these late-90s GM vehicles, VIN programming isn’t just a convenienceโit’s critical. The ECM is the ‘brain’ that communicates with the transmission, the anti-theft system (Passlock), and various sensors. Simply installing a non-programmed unit from a junkyard will almost always result in a no-start condition or major running issues. By programming the module to your VIN before we ship, we ensure all these systems communicate correctly from the moment you install it. This pre-programming step saves our customers hours of frustration and hundreds of dollars in dealership fees.”
Frequently Asked Questions
How do I provide my VIN?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. You can typically add it as a note during checkout or send it to us in a message. We cannot ship your part until we receive this information.
Is this part difficult to install?
The physical installation is straightforward for someone with basic mechanical skills. The ECM is located on the left-hand (driver’s) side center dash. However, after installation, you will likely need to perform a simple ‘Security Relearn Procedure’ to sync the new ECM with your car’s anti-theft system. This procedure can be done without special tools and instructions are widely available online.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the original ECM (e.g., codes P0601-P0605), this replacement part is the correct solution. It’s always best to have your vehicle properly diagnosed to confirm the ECM is the root cause of the problem.
What does ‘programmed’ mean?
Programming, or ‘flashing’, means we load the module with the specific GM factory software that your vehicle’s VIN requires. This includes all operational parameters for the engine, transmission, and emissions systems, ensuring it works perfectly with your car’s existing components.
How can I be sure this fits my car?
This ECM is a guaranteed fit for a 1999 Oldsmobile Alero or 1999 Pontiac Grand Am equipped with the 3.4L engine, specifically replacing a module with the ID number 9361733 printed on the label. Providing your VIN allows us to double-check and confirm perfect compatibility.
