- Engine stalling, stumbling, or running rough for no apparent reason.
- Complete no-start condition where the engine cranks but won’t fire up.
- Noticeable decrease in fuel economy.
- Failure to pass state emissions testing.
- Erratic automatic transmission shifting.

Absolutely not. The main benefit of our service is that we handle all the programming for you. Using the VIN you provide, we flash the module with the correct software for your 2006 Envoy’s specific configuration. It will be ready to install and start the vehicle upon arrival.
Where do I provide my vehicle’s VIN?
You can add your 17-digit VIN to the notes section during checkout. If you forget, don’t worry! We will contact you via email after your purchase to request the VIN before we program and ship your part.
What if my original part number isn’t on your list?
The part numbers listed are the most common, but there are many compatible service numbers. As long as your vehicle is a 2006 Envoy with the 4.2L engine, this module will be the correct one. The VIN programming is what ensures perfect compatibility.
Is a security relearn procedure required?
Yes, in most cases you will need to perform a simple security relearn procedure after installation. This allows your vehicle’s anti-theft system to recognize the new PCM. It’s an easy process that typically takes 10-15 minutes and involves turning the key on and off in a specific sequence. We can provide instructions for this procedure.
