5.4 running sluggish in low gears.

I recently took my 2010 expedition 5.4 to Ford to get an oil change. After I got the oil change my vehicle started driving very sluggish in low gears. I took the truck back to Ford to have to look at it. They said I need lifters, followers, and few other engine components. I decided to take it to a local mechanic and they continued to tell me that it’s not the lifters. The problem is the don’t know what the hell is wrong with it. They ended of taking 2 knock sensors and hung them from the intake manifold. The truck drives much better but the check engine is on 24/7. Any advice on what the hell is going on? Thanks

Did it exhibit any of this behavior before the oil was changed?

No it didn’t.

No it didn’t.

So if you had not changed the oil, would it still be running as before? Yes. Who changed your oil?

Took it to Ford for the oil change.
