I need some help, I cant get my car to pass CO emissions. The car is running to rich. Any ideas??

The Camaro only has 27k miles.

We have an old Cadillac like 91 and we put a bottle of alcohol in the gas tank when we need to get the emissions tested

Odd you can't pass emmisions, engine hot enough ?, Cats are bad ?

have you tried it with the stock maf back on there? My guess would be your tune is a little off.

You have the OBD2 plug test? I pass emmisions in TX with long tubes and a ORY since my rear o2's are deleted.
I have the Granatelli MAF, so I can't see that causing it. You have long tubes and a tune, so your rear o2's should be deleted if not have the tuner you went to delete them so they no longer read when the plug the OBD 2 in. I had mine deleted since I have no cats.
Only thing I can think as your tune is set too rich(have to go get the tune redone).
