Emissions Testing (NOx)

Hi all,

I own a 1985 Toyota Supra that refuses to pass the GA emissions
testing. On the first test my NOx was above the limit on both the 25/25
and the 50/15 test. After the first test I SeaFoam'd the engine in
every way possible and used the "Guaranteed to Pass" magical liquid.
Ten days later I took the second test and my "HC" was much higher on
25/25 and my NOx passed on 25/25. NOx still did not pass on 50/15.

1) Did the much higher RPM values probably significantly affect the
values of the test?
2) What is the best (even temporary) way to push my NOx into the
passing zone?

(Test results are below)

All help appreciated,
Alex

Um, did John Kerry test your car?

Proper ign timing and a functioning egr system are the number one issues
with high nox.
