Idle adjustment/ throttle body help

[Jig]

Any way to adjust this type of throttle body? Doesn't have the screws or the black Allen key access

Car runs mint when cold but once upto operating temperature the revs are too low causing it too shake too much

Maybe try and clean the idle air control valve on the back as if it is a little bit clogged it may dip your rpms.
It could also be the MAF sensor, but if the car is running good i doubt it.
Lastly you can try and open the butterfly some more by adjusting the screw and nut that the accelerator cable/spring mechanism hits when the accelerator is not pressed. This way you can tweak the idle RPMs by leaving the throttle a tiny bit open but this would be my last option as it shouldn´t be done this way.

No you cant adjust the timing or idle on the coilpack engine.

First with erratic idle air issues perhaps it may be cost & time efficient to carefully search for vacuum air leaks in air hoses paying particular attention to the servo hose & crankcase ventilation valve operation/hoses together with exhaust leaks.

Where air leaks suspected quickly test by momentarily clamping relevant hose whilst it is idling.

Good will hunting.
