02 civic system too lean
looking to fix a problem before the turbo setup gets added. CEL "system too lean (bank 1 sensor 1)". Also have a wideband on there and its runnin lean on startup and full throttle, when it should be rich I believe. Replaced map sensor so far haven;t found a vaccuum leak, gonna do a fuel pressure test the next time i can work on it. Any other suggestions or help would be greatly appreciated.

what kinda setup do you have? on a 02 civic, the best thing is to convert it to a return style system. use a walbro 255, and a aeromotive fpr and upgrade injectors of course. and what ems?
and you're gonna need to modify your stock rail or get a new one fabricated in order to make it a return style.
