350z 2004 running rich wideband says lean
Hey guys I’ve never posted on a forum before but here it goes
I have a supercharged 2004 350z with an HKS supercharger
I had recently swapped the engine and moved all my bolt ons over
when I start the car i get a an idle AFR of around 14-15 on my one bank
the other bank reads “LEAN” and says there is a split difference of 5-8 between them idle is good until that 02 sensor reads the lean bank then the car starts dumping fuel causing a bad idle (I assume)
there is fuel comming out of my tail pipe (passenger side) and all of my plugs are black
If anyone has any advice that would be much appreciated
thank you
