Engine Performance problem
2005 Ford Escape 6 cyl Four Wheel Drive Automatic 88000 miles

When driving at between 50 and 60 miles an hour,
I let up on the gas and the rpm drop and come back
up then drop and come back up several times. I tried one time to put the car and neutral and the rpm did
not drop all the way down. I had the code checked
and no codes are showing?
