Ive done searches but haven't found what I need....

I bought a 92 hatch with a 95 USDM B18C1 (GSR) motor. The guy I bought it from said after he did the swap, he took it to get the emissions done in Maryland and failed. It came up "diluted sample". They told him to go drive around for a while and warm up the cat. After testing it again he got the same thing. So he just gave up and gutted the cat, never getting emissions done. The cat had about 150k miles on it.

I live in Virginia and need to pass VA emissions test. Im not too worried about passing the visual test, but I am concerned about passing the sniffer test. If you fail in VA, you must spend either $450 or $600 (not sure) to get a waiver.

So Im wondering what I should do to pass. Currently the car has a gutted cat, so Im wondering if I buy a carsound cat, will this work ok? Second, the car has an adjustable fuel pressure regulator, what psi should i have the fuel rail at?

Has anyone ever heard of a "diluted sample"? What does this mean? And what can I do?

thanks all

Scott
