Let me first introduce myself. Hi everyone my name is Aaron and live in San Francisco cali. I own a 98 200SX SE....Yeah...SE.. I wasn't able to buy the SE-R because I bought it Jan. "99". By that time the SE-R was sold out. So I just planned on doing an engine swap in the near future. Hopefully to have pictures soon. Well, my question is does anyone know how to reset the "service engine soon" light??? I accidently turned on my engine without the air sensor attached. So now I have my engine light on. I tried disconnecting the battery for 10 min and its still on. Someone told be to un-plug the comp. for 10 min and connect it back and it should work. I haven't tried it yet. I was wondering if anyone else has any other ideas.
