If you have a friend near with the same car, try to swap out the AFM and see if it makes a difference.

Look at the crank pully and get someone to press clutch in.It will move out
/ in when clutch is pressed if thrust bearings are gone.
If it does move stop driving it untill you can fix it or it will scrap the block/ crank.
If thats ok its probably to do with the AFM as loading changes on the engine when clutch is pressed in.

Basically what happens is when the cars cold and I press the clutch, the rpms decrease by 200 but when cars fully warmed up the car stalls out with clutch pressed.
The car seems to drive fine other then this and this only happens when I press the clutch in neutral.
No weird knocking or ticking noises.
One of my mechanics checked the obd codes, and said I have a code 24
( bad intake air temperature sensor/ AFM), could this be the problem or do I have crankwalk?
So far I've done the following:
-Replaced clutch and flywheel
-cleaned iacv and throttle body
-checked crank pulley for visible movement and there was none, also had a mechanic look at it with a prybar and he said no movement what so ever
-Tried several idle reset procedures
Any help is greatly appreciated..

Remove the sump and check the thrust bearings.I think you will find they are damaged and so will be the crank

Have you sorted the error code yet?

You can try measuring the play with a dial gauge as there will be a maximum spec in the repair book somewhere.
