2010 V6 XLT random misfires once up to operating temp

[BeemerNut]

Presently at 140K trouble free miles. Cold starts and warmup driving light throttle city driving warmup before entering the highway a perfect running engine. Once in a while including ten highway miles at 60-70 mph everything is normal. Park and restart half and hr. later then having random engine misfires. 

Another time the same driving loop again at operating temp having random misfires at speed dropping in Hp with a softer throttle pedal yet floor it accelerating hard, downshifting and up to 5,000 rpms pulling hard from 70 to 90 mph a strong healthy engine with zero misfires. 

At traffic lights idling city driving in drive again the random missing like 2 to 3 times a second to once every 5 to 10 seconds randomly dropping cylinders a couple quick random cylinder misfires. With the AC on idling in drive you will get jerked around the idle rpms being correcting from the dropped misfire rpm's, only talking a app 75 to 150 rpm's rpm's variations. When running normal the rpm's are steady and solid even when the AC cuts on and off cycling.

Disconnecting the EGR connector, the connector next to the EGR to the left of it and lower by the hard plastic PVC tube connector and at the outlet after the air filter the same random misfires.

New COPS (Motor Craft not clones), plugs, crank trigger sensor, EGR valve as well the 90 degree pipe that pokes into the intake cleaned, still the same random misfiring issues. No CHECK ENGINE LIGHT or WRENCH LIGHT at the dash being the pisser then able to read a code and correct the issue. Engine coolant temp holds solid just below half gauge as when new. 

The only thing I have not clean the air mass flow sensor as it looked dry and clean with the automotive "Endoscope". Mass meter spray can possibly mess up Mass Flow Meters. The sensor at the back of the intake manifold up top and horizontal pointing toward the firewall taking a dump on me? 

====================================================================Different year 2004 Escape V6 issue solved=========================================================

The air mass flow sensor on the 2004 Escape had one end of a thin wire the thickness of a double hair with a tiny looking resistor bump in the middle, the end of one hair wire was floating around making random contact to one of the larger solid wire posts out to the connector of the sensor. It would read low resistance yet random contact caused by engine vibrations and temp swings.
