Also get a code reader on it incase anything obvious comes up.

as said you can also buy some stuff think it goes in the fuel to stop smoke its a short term fix but might help you get a ticket

as above

oil and filter right before the test.

Or move to a country with no emissions testing.

I'm sure the Ecu temp sensor can cause the engine to run rich if faulty as it can't sense if engine is cold or hot.

As above but also buy a new CAT and lambda sensor
