You would do as well to ask on a Ford Mustang board; as the Mustang is closer to your car than the B-body Impalas found here. Our cars have no computers, no V6 engines, and no rear wheel drive. We have carburetors instead of EFI.
You have a Lumina rebranded an Impala in 2000. It is an Impala in name only as it is based upon the Lumina's W-body platform.
