Idle unstable, what to adjust?
 

Hello,

Installed pnp to my '92 1.6 JRSC yesterday and we've been tuning the VE table pretty succesfully today. Sparksettings are like they were on basemap - no change there yet before dyno. Only problem at this stage is the idle that keeps wandering between 800 - 1200rpm cold and warm. Haven't touch those original Idle Control and Idle Control (closed loop settings). What should be checked or tuned next?
AFM is removed.
We are pretty lost with this idle at the moment.

Hi Timo!

First thing to do - if you don't already have - get the hires code.

You will find lots of info by searching for "idle" "idle control", in this forum.

Look around a bit and you'll find :-)
