The car accelerates in P or N (1900 RPM)

Hello, my car has just come out of a year-long exhausted repair, we are talking about big heads, pistons, new OEM sensors, timing belt, tension-er, oil, spark plugs, OEM coils, MAF new, Etc.

The moment I start the car it goes up to 1500 rpm's to 1900 rpm's (parking), then if I change the gear to "D", the revolutions go down to 900 rpm's. And I can drive normal. Then I put the car back in P when parking and climb up to 1500 to 1900 rpm's.

The same happens in neutral, the revolutions go up.


Now read this: When I turn on the car and the revolutions go up I must hit (accelerate) the accelerator quickly and lower to 1000 rpm's. (The right thing).

Fault found: I could find that the throttle spring is too tight and the throttle does not return to its position, so I lubricated it with WD40 and it worked a bit.

Note:
I also cleaned the EGR valve (It was very dirty), but it is still the same. The IAC valve is new and I can hear it working. One sensor that did not change was the "throttle butterfly".

The auto does not give scrap errors, but I have not reviewed readings nor do I have one right now.

I have no loss of power, the car works amazing is a powerful machine no longer has a catalyst.

It has a cold air intake and the MAF post, so I put the original filter box back but the problem is the same, so this is discarded.

The acceleration body is clean.

Questions:
1. Should I replace the EGR valve?
2. Is it a vacuum problem, if so, what hoses do you share with the transmission?
3. Any suggestions this sometimes scares and it seems that the problem must be some nonsense?


I have included a video to illustrate, thank you.
