Just got back from my local emissions test. HC was ok, CO waaay low... but I got killed on the NOx reading. No, not nitrous oxide.
Any good suggestions for things to look for, check etc?
The car: 1990 Honda Civic Si
The engine: 1989 JDM Civic ZC
The ECU: 1989 Integra 5 speed
I don't have my manual here to see what the factory recommended. But I am in a crunch as I have to pass before Wednesday when I head to court to explain why the car hasn't been inspected in years..
TIA
Jim
