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

Test Results Format: [[TEST #]] [[VARIABLE]] = [[25/25 TEST]] + [[50/15 TEST]]

Test #1: 12/19/06 Test #2: 12/29/06

[#1] HC-ppm = [39/157] + [40/162] [#2] HC-ppm = [98/157] + [36/162] [#1] CO-% = [0.32/1] + [0.35/0.91] [#2] CO-% = [0.25/1] + [0.23/0.91] [#1] NOx ppm = [1315/1121] + [1622/1227] [#2] NOx ppm = [1117/1121] + [1381/1227] [#1] RPM = [1909/1500-3000] + [1771/1500-3000] [#2] RPM = [2902/1500-3000] + [2967/1500-3000] [#1] CO+CO2% = [14.1/6.0 min.] + [14.0/6.0 min.] [#2] CO+CO2% = [12.9/6.0 min.] + [13.2/6.0 min.]

Make sure it has egr flow, if not, correct it. If so, put a converter on it.
