Dan_Austin, everyone I know (personally) in CA has problems when it comes to smogging. I don't know anyone that can take their 280 in and it pass without adjustments of some kind. That is my goal. To have a worry free FI system if there is such a thing. Our 2005 Altima has 171000 miles and everything is perfect with it, knock on wood! No FI problems at all. It is just a pain anymore, due to health issues, to worry about getting the Z to pass. I am a member of the online "classiczcarclub" and was able to work out most of the problems with my FI. I may just be complaining a little also. I have to lean the AFM, retard timing, and raise the idle for it to pass. It would be nice to not have to do that anymore is all Im trying to say. Like I said maybe Im just complaining about nothing. It starts every time, idles perfect, doesnt over heat, 21 mpg combined. Ok someone go ahead and say it....stop worrying about it?
