Increased idle speed for CO test rpm 2500-2800
CO content @ increased idle speed vol % 0.3
lambda at increased idle  - 0.98-1.02

any chance you could also put the data for the 3.5 efi and the 4.0 & 4.6 that would be even better

4.0 & 4.6 are giving the same results
but 3.5 efi is

CO Level at idle speed - tailpipe  vol% CO : 0.5-1.0 adjustable
HC level at idle speed - ppm 300
CO2 level at idle speed - vol %CO2 13-16
o2 level at idle speed - vol % o2 0.5 - 2.0

no cat so no other readings

Hope this helps
Steve
