If your 2011 Regal is acting up—rough idle, no start, or check engine light woes—the issue might be the brain of the engine.

This is a remanufactured GM Genuine Parts engine computer, part number 12651993.

It's been completely torn down, cleaned, inspected, and rebuilt with new components where needed, so it works just like a brand new unit.

The best part?

We'll program it with your specific VIN before it ships, making it a true plug-and-play replacement for your car.

It also crosses over with a ton of other part numbers like 12637106 and 12642843.

No need to take it to the dealer; just swap it out and get back on the road.
