off the chart lean can cause the HC levels to be way high , I see this all the time that guys want to argue that there car is running so rich is burning their eyes but yet they have no wideband and when I finally get a wideband on it , its actually running WAY too lean , fatten the tune up in the 0 to 2.5 volt area of the MAF transfer and problem fixed
I find it very common when running calibrated meters that they run way lean from idle to about 1.5 to 2 volts
