Question: I have a 99 Infiniti I30 with the service engine light on. I read the above links where it tells you how to check the light with the blinks, etc for a 4th get maxima. But when I pulled the panel off to expose the ECU, the little white sticker is called idlespeed adjustment and then says "low - high - self diagnosis" and there isn't a small flathead screw too adjust. The sticker wasn't broken thru either. Is there something I'm missing? I was assuming the I30's and maxima's are the same. Did they change something for this year?

 

Yes, the method for checking the codes it is different from the other 96-98 ECUs.

Since you have a 99, just save yourself the hassle and have Autozone check your codes.
