Hi guys,
I have a 89 TTA
Stock exhaust, green stripe injectors (30lb)
I set the fp at 42-43 psi.
Using an emissions chip.
My 02's were showing around 200 mV
Block learn was about 137
integrator around 130.
I failed at 25 mph and 15 mph
At 25 mph
HC 152 std ppm, 157 ppm FAIL
CO% .97 std, .60 PASS
NOX 1082 std ppm, 2988 ppm FAIL
Dilution >6%, 14.7% PASS
At 15 mph
HC 157 std ppm, 154 ppm PASS
CO% .88 std, .48 PASS
NOX 1184 std ppm, 3134 ppm FAIL
Dilution >6%, 14.5% PASS
High NOX and I am real close on HC.
It has the stock cat on it ...my car has 75K miles on it.
It has a power plate, but I drilled the hole for the EGR.
Any advise is appreciated. They mentioned something about the EGR valve...I will take it off and see if it is carboned up and test it with the mighty vac.
Should I put the stock chip in? instead of the emissions chip?
Help.
James
