Lets see if this works....Just looking if these values are withing spec. I know I have a misfire on #6 and the CEL comes on intermittently .....I have to pass inspection this thursday so I need to figure it out.....
Photo of the screen....if that will do?
btw this is in normal driving about 20 miles both highway and rural (no city) one way
Thanks in advance:

not sure how picky they are, the long term fuel trims are a little high normally they should stay in the -10 to 10 range, closer to 0 the better. I'm not too familiar with emissions testing areas. Let it idle at operating temp and see what the short term fuel trims do, if they are high at idle you need to be looking for a vacuum leak.

OK Did as you said . at idle these are the values: the average includes 2500rpm as described on the interwebs.....
