on the way to work today my check engine light came on, so i had it checked out and this is what its coming up with.
PO171 bank 1 too lean
PO174 bank 2 too lean
PO602 control module programming error
im guessing its showing lean b/c of maybe a vacuum leak? according to my wideband it is not running lean so im puzzled about this. i do know one of my vacuum lines is a little rough looking and could possibly be leaking so im going to change that for sure.
but what about the last code. why on earth would it be saying i have a control module programming error. im running the sniper software. tune was custom done by a sniper dealer who is also a member of this site. i really dont think there is anything wrong with the tune but maybe it could be? anyone have any ideas?
