Idle issues...

[helderteixeira]

Still with issues adjusting idle... think now I know where's the issue... I have adjusted the screw to idle 900 rpm. After 2 or 3 minutes drops to 700 rpm. If I reset the throttle position (ecu)goes immediately back to 900. After 5 minutes goes back to 700... sometimes stays longer but as the time goes reverts to 700. Any thoughts?

Nick,
Erratic but not much let say when warm it fluctuates from 780 to 890 continously up and down between those values... but I don't have the experience to know if it's acceptable this variation? I'm not sure what else can I do here "alone" in Dublin

Hi Sagi,

Thank you, to clear my thoughts... I was exactly pointing to the Dallas Nvram.
I have clean a big number of earth connectors... just peace of mind.
I was about to order the dallas ram, remember a post a while back with someone with issues with lambda and adaptatives, turns out Dallas... I have order the DS1230AB-70IND+ see if works...
