2010 ss/tc air fuel ratio cruising jumps from 14-15 plus at a steady speed..

is this correct or is something up? 1st time i have swithched to the air fuel ratio gauge.. has 900 miles on it..

 

a/f during normal driving goes between 14.6 -15.3 only during wot it will drop to 10's

 

Ive never seen a/f in the 10's. Yes while cruising the a/f can swing around from the mid 14s to mid 15s. Something as little as the a/c compressor kicking on or catching a cross wind will change the load on the motor therefore causing the small variation in a/f

 

ok, seems normal then.
