Open each menu one at a time and look at the possibilities. I have not used your scan tool so I cannot help you find it without being there

You cannot show me the exact readings at the time the code set. That's what I need to see what triggered the code

The high percentages on long terms are what triggered the code.

You have a vacuum leak somewhere. It could be intake, pcv or hoses but as long as the percentages are that high, the codes will stay active

OK I did find an issue with a hose. Trying to get a new pcv thru ford. Can't use just a regular one. Right now at idle I have bank 1is 12.0% bank 2 is11.0% they jump around a lot depending g on driving. Negative number to a positive. On the intake gasket part can one try to tighten it at all or don't help. Wasn't sure what % I had before the lights came on. Hadn't scanned it then. It is running good at this point. Thanks

Idle is the most important time. It needs to be the same at that time as well

OK will try the new pcv tomorrow and I might check intake bolts to see if there tight. Not sure about any other hose. Someone wants me to make a smoke machine to test for leaks so that might be next
