I managed to get the screw out and adjust the TPS.

To bad, the hardware store didn't have M4x12 hex bolts so I had to use screws again.

Unfortunately it didn't help my problem

I managed to set the timing by adjusting the idle way to high, shorting the terminals to go into diagnostic mode and lowering the idle extermely slowly.

If I did it to fast it the idle would start to bounce or the engine would stop running.

The timing is spot on now but the car still doesn't idle properly.

When starting it

(hot engine) it bounces between 500 and 1500 rpm most of the time it stabilises itself

(around 900-1000 rpm) but sometime it just dies.

The same symptoms apear after revving it a bit, it always starts to bounce, stabilises itself most of the times and sometimes dies.
