Default Kem tuning error p0174?
System too lean bank2 is the description of this error. What would cause this problem? We are running the kem tuning and I'm thinking its an issue with the tuner itself. Anyone else having this issue?

I do not have that tune but I have had that code because of an after market intake leaking air at the throttle body, Do you have an aftermarket air intake

If has an aftermarket filter, but not intake. It also has a banks muffler... I would think that if it was something like that it would do it all the time and not so intermittently?
