I need to increase idle speed

[manimal]

I have a hunting on idle problem still as some of you might know from my previous posts.
I have noticed in this icey weather my idle speed has increased about 100k.
This has stopped my hunting completely.
In normal conditions it idles at about 600,in this icey condition it is idling at 700.
It seems to like it at 700,runs sweet.
Is there any way of adjusting the idle speed permenantly ?

tech2 option think it allows a 200rpm up or down from standard

Is this something that can be done on OP-COM too? There might be someone close by that can help you out.

sounds to me like you have a speed sensor on the way out either crankspeed or cam speed.

Which engine do you have ?

I have the Z18XE (2003
it had a new (not Genuine) crank sensor fitted not so long ago when i had a replacement head fitted.This is when the huntiing first started,Wiring looks a bit rough too.

Non genuine crank sensors are mostly prone to giving problems, ask any mechanic and he'll tell you not to use a pattern part as the output signal is all over the place when viewed on a scope.
