idle isues

Thom

HHello, I have some problems with idle control. It seems like the idle position degrades at higher rpm and sometimes randomly. It happens in the higher rpm range more often, but it can happen randomly. Usualy I have to restart the engine a couple of times to fix the problem,
Times when it happens:
3:26-3:33 High not correct rpm when at idle
4:38-4:54 slow and high rpm when at idle
7:24-8:22 very high rpm when on idle
9:32-9:46 Very high rpm when on idle
9:50-10:00 engine off and start engine idle (850rpm) is correct and the idle(18%) position is correct.

The main issue - incorrect TPS 0% adjustment, which leads to intermittent Idle detection.

Also, I've adjusted some other parameters related to the idle mode.

Thank you, I will try these new adjustments.
My TPS is very noisy, especially in lpg mode voltage jumping by 0.1. Thinking that the wires are the problem, planning to run new shielded wiring, so we should expect good results.
