smog buster

[Masashi]

Hi, I am Masashi Japanese who live in Las Vegas NV.

I have 72' 240Z and in here NV. I need to pass smog inspection

for resistration.

I took air pump and exaust recycling system off.

Engine is quite good condition and running good but CO and HC

is too high ( HC ppm is 4361 , CO % is 12.00 at 700rpm)

If somebody has good idea to reduce smog, please let me know.

I look forward to sombody's help.

Regards.

You will probably have to put the pump and your EGR back on.
