Infiniti G20 High HC Emission Test

1996 Infiniti G20 HC emission test. Failed result was 2 ppm above the limit what is the simpliest way to lower HC number?

Answer:

If your Infinity G20 does not have any defective emission components, heating up the CAT would help lower HC. If your Infinity G20's catalytic converter was heated properly before the smog test, i.e. you drove your Infinity for at least 30 min before the test and it was not cold prior to the smog check, heating the CAT further might cause other failures.
