2001 clio ph2 1.6 16v weird idle problem

[Turbomaskin]

Hello. I have a idling problem on my clio. Engine code is k4m 744. When engine is hot idle drops to somewhere between 450-550 rpm and jerks alot (see video). Cold starting does not work as intended either as the idle after cold starting is 900-1000rpm. The car runs well when accelerating. Can jerk sometimes when cruising under 1400rpm. The car is not throwing any fault codes.

What ive done with the car:
New sparkplugs
New ignition coils
New map sensor
New intake temp sensor
Both o2-sensors are new
Cleaned crankshaft position sensor
New intake manifold gaskets
New throttlebody o-rings
New air filter
Cleaned throttle body
Have checked timing with the proper tools and its in spec.
Have tried to do a battery reset after changing everything, made no difference.

Has anyone had the same problem and how did you fix it?

Video is linked on post

The car was like this when i bought it 1 month ago so i dont know if anything sudden happened

I had bad idling issues where the car was almost stalling at traffic lights, etc - and replacing both exhaust sensors fixed the issue. As you've said that they have already been done - that's now unlikely.

Do you know if they were branded items or something else?

Here is video from engine bay while hot. Very rough running

Maybe I’m going deaf in my middle age, but that sounds ok?

Its quite hard to hear on the video but its very jerky in real life, almost feels like its trying to strangle itself. Anyone familiar with how the electronic throttle bodies. Should they move and adjust the idle or do they just lay on the ”limp mode” spring whete the flap is not completely closed

Did you do the throttle body adaption? There s a procedure to do if not gime me a shout and will tell you about .

No i havent done that, would be great if you could tell me how. Seems like everyone has different answers to that on other threads hahah

I do this sequence 2 time in row and it goes like this :
From standstill you change gears at 1500 rpm so 1st 1500 , 2 1500 , 3rd 1500 once you shift into 3rd at 1500 you put your foot down and hold it there until it reaches 3500 , your car is going to be underreved but it ok once you are at 3500 lift you foot but leave it 3rd and gently and i mean gently brake until car is at idle speed , repeat it again and you have your throttle adapted.
I learned this from a friend and i normally do it every 4 months on my car ( i have an Ramair filter ) .

This won't do anything.

Unplug the TB and leave it disconnected for 30 seconds, once reconnected turn ignition on and leave it for 30 seconds before starting. When doing this you hear the TB running through a sequence (on the 1.2 16v anyway!)

Or plug in diagnostic machine and reset adaptations

Couldnt find any option for resetting adaptations on my icarsoft pro. Do you need another diagnostics tool for that
