I just installed a wideband on my car before I put in a supercharger. I just wanted to know if the AFRs on my car are normal.
When I start it cold (over 9 hours of sitting) my AFR is in the 16s.
As it warms up it drops. At idle it 14.7-15.3
As I'm cruising (say 60 mph) my AFRs jump constantly from 14.7-15.5.
Just want to know if any of this behavior is normal for a stock, 1.6 car.
