Please Help... Can't Pass Emissions test, High Carbon

[Boostin91TSi]

Hi all, I have already been to the VA state Emissions test at my old dealer and keep failing due to the car emitting high carbon. I am thinking that this has something to do with my fuel mixture? I had a S-AFC in the car, but took it out because of too many problems and my friend needed it back. I have no idea at all as to what to do. I have my thermostat back in, but could it be my plugs? I had oil in cylinder 1 spark plug well and already removed the oil. I guess I have to change the plugs, but that can not be it. There has got to be more than that. Could someone please help me? I have already searched before posting this.

Thanks All!

"TurboXS RFL Blowoff Valve" Is that recirculated?

any boost leaks?

CEL codes?

"550cc Injectors" are those installed?

How old is the catalytic converter?

How is your compression?

Burn much oil?

How much are you failing by?

It doesn't take a huge problem to fail a sniffer test.

Don't bump! If someone were going to answer, they would have.
