Okay running WOT I am seeing my bank 1 LT-FT going +17%...and ST-FT slowly catches up and will go -17% at higher speeds.
Bank 2 just floats around 3% + and -
At idle and low rpm cruising seems stay in good range...anything over 3k rpm it's starts get a little jumpy on bank 1
Any ideas on where to look.??. no CEL but im scheduling dealership to look at since it's under warranty..car has less than 4k miles
