Ford COP systems are like that. If there are no codes, slight misfire/surge issues can be difficult to trace. I’m sure the technician was as frustrated as you at not being able to pinpoint the problem. These are OE engineering issues usually, not a lack of effort or competence. I would suggest a throttle body cleaning and a careful mass air flow sensor cleaning. Next step might be a "smoke machine" test to look for intake manifold vacuum
leaks.

Stabilizer bars. You may know them as sway bars or anti-sway bars. You may know them as roll bars or anti-roll bars. They’re all the same thing, and it’s generally understood they improve handling … but how?
Any time a vehicle is turning, the forces that act upon it cause the body to roll, sway or tip away from the turn. It’s the laws of physics at work. In extreme situations, these forces can cause a vehicle to tip over, though that’s generally only the case with taller trucks and vans, and rare at that. You really have to be moving for that to occur. The real factor is how they negatively affect handling and how a stabilizer bar can prevent it from happening.
These components should be high on the list of parts you sell.
