Hey guys, I have an interesting problem. The other night my 2006 Whipple GT gave a PO175 Bank2 Rich code. Three days before that I added a Breather to the passenger side and a UPR catch can also with a breather on the drivers side. Also my Idle goes between 500 and 900 RPM. By me eliminating the PCV hoses did I do something to the Idle and the Air/Fuel mixture? If this helps, I did a data check with engine running and this is what I got.
LT FTRM1 -7
LT FTRM2 Between -7 and -11 I noticed when the idle surges so does that number. Thanks for any help.
