When did Chevy switch to EFI?

Chevy’s Switch to Electronic Fuel Injection (EFI)
Chevrolet made the switch to Electronic Fuel Injection (EFI) in the mid-1980s. This transition marked a significant advancement in automotive technology, replacing traditional carburetors with a more efficient and precise fuel delivery system.
The introduction of EFI brought several benefits, including improved fuel efficiency, better cold-start performance, and reduced emissions. It also allowed for more precise control over the air-fuel mixture, resulting in enhanced engine performance and drivability.
The shift to EFI reflects the ongoing evolution of automotive engineering and the continuous pursuit of more efficient and environmentally friendly vehicle technologies.

When did EFI become standard?
