Is Your 2012 Camaro Running Rough? The Problem Might Be Its Brain.
There’s nothing more frustrating than when your powerful 3.6L Camaro starts acting up. One minute it’s running perfectly, the next you’re dealing with a stubborn check engine light, unexpected stalling at intersections, or hesitation when you hit the gas. These aren’t just annoyances; they’re classic signs that the brain of your engineโthe Engine Control Module (ECM)โis failing. After years of heat cycles and vibrations in the engine bay, the delicate internal circuits can degrade, leading to a host of performance issues.
Expert Pro Tip From 20+ Years on the Floor:
Before you condemn your old ECM, take five minutes to inspect the main engine-to-chassis ground strap. I’ve seen dozens of vehicles towed in with classic ‘bad ECM’ symptoms that were actually caused by a corroded or loose ground. A poor ground creates electrical chaos, starving modules of stable voltage. Cleaning the contact points with a wire brush is a simple check that can save you hundreds of dollars and a lot of diagnostic headaches.

We are providing a genuine GM Engine Control Module, part number 12642665, that is professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN). This critical step ensures that the module communicates perfectly with your Camaro’s other systemsโthe transmission, the anti-lock brakes, and the security systemโright out of the box. You get the latest software updates from GM, which often resolve underlying drivability issues the factory addressed after the car was built.
Common Symptoms of a Failing ECM:

- โ Engine stalling or shutting off while driving
- โ Rough or erratic idle
- โ Noticeable decrease in fuel economy
