OK, I just installed a cold air intake on my '97 Nissan 200sx. I got a Mr. Gasket cold air kit from Napa that was intended for a Civic, but I just used the filter element after the mass airflow sensor. After installing the cone and starting my car, the check engine light came on. For a few minutes it smelled a lot like gas around my car, but that went away soon. So I am wanting to know what the deal is with the check engine light. Have you guys done a cold air, only to have it do the same? I didnt remove any vacuum hoses, so I cant really see a reason that the computer would register any sort of problems. I guess that its possible that the o2 sensor or some other computer device could measure a lean mixture due to the extra air, and come up with a problem, but I thought that the computer was supposed to fix that. Anyways, I was wondering if anyone could share some ideas with me. I am have only put about 50 miles since installing the cold air, and think that I should check the OBD2 for a readout of what the comp thinks is wrong, but i need a good link to a page that could tell me what a readout would mean. I have done this before, but am unable to find the page with readouts for my car. As always, any help is greatly appreciated.
