The Monroney label (window sticker) of my 1999 Riviera states that the car came equipped, at no extra charge, with the "Eastern States Emission Package." It was originally delivered to a dealer in upstate New York when new and and sold there.

What is this Eastern States Emission Package and what additional components were added to the L67 engine for it to be sold in New York back in 1999? Does it detrimentally affect performance, mileage, oil consumption, engine life or anything else? Since the car is now owned by me, and I live in the midwest where emissions targets are less strict, is it possible to remove these components? If so, who could do it?

I'm not quite sure what was installed or changed on the car. It appears that it was something that was released nationally by the EPA in 2001, and in the Eastern states in 1999.

The link below is a read on it. Page 50 if it doesn't send you there.

I work at a Buick dealer. If you want, PM me your complete Vin # and I can run a Vehicle History Report on it and see if it tells me anything?

Maybe someone else knows about it more....

I put my car on the scanner and the pcm reads out California compliance obd2 but my car has been in raised in Houston all its life. Does anyone know what that means

It means your car will pass emissions in CA. All new cars sold in the US must meet this standard.
