Just to concur, my 1994 Infiniti G20 failed the smog inspection the other day.

The tester noticed that my timing was off. It was at O degrees, but it should've been 15 degrees BTDC.

It took it home, and set the timing to 15 degrees, took it back to the smog inspection "test only" station, and it passed.

He said my timing was at 13 degrees, not 15, but he said you are allowed to be off 3 degrees + / - .

I noticed when comparing both inspection sheets that the 15 degrees made a surprising difference.
