Hesitates above 2000 RPM. Replaced fuel pump, relay, fuel pump driver module, spark plugs, fuel rail pressure sensor, could it be the throttle position sensor?

My car when I started feel
Like someone is pressing the gas and now when driving jerking

When accelerating I get a shudder, like running over small bumps in the road. Sometime it has trouble shifting. It is worst when it is hot outside.

Changed my sparkplugs and coral pack now what

I have ford escape 2003 v6 3.0L. While i was moving the car the engine will jerk. Previously there was a problem with the battery light flashing and had changed the alternator and the problem of the battery light was resolved. But the jerking problem is not solved. I already changed the spark plug but i found there was a bit oil licking on spark plug part. Is that the cause of the problem or is there another problem?

Sometimes my vehicle starts to not shake but hesitates going like gallops forward and does not let me go above 20 mph kind of acts like it's in limp mode but there is no engine check light that comes on. I then have to turn it off for like 15 min and once I start it up again most of the time it goes away and drives normal.

Steering wheel jerked erratically finally stopped power steering assist failure on cluster now no power steering

My 2016 Ford Escape SE is equipped with first generation SYNC- meaning no navigation system, touchscreen capability, OR automatic wifi updates and the system has begun acting glitchy. Turning off Bluetooth when no one has touched a thing. Or dropping the connection to my android when it was connected just fine 5 min ago. It probably needs to update is my guess , but I can't afford to take it to Ford dealership at the moment.
It's running the 5.8 version and I found a 5.14 update on the Internet. BUT "I found it on the Internet" sounds like another way of saying "OOPS" so you might understand my hesitation.
Im trying to find alternative strategies to debug system. Ideas?

Hesitation going into reverse have to rev engine
