When my car is cold the idle is about 1200 RPM. OK
As it warms up it drops to about 700 RPM. OK (on the car tach)
On hot days like today it idles about 250 - 150 RPM until it just stalls.
I've tried adjusting the idle screw on the throttle body but it doesn't seem to do anything opening it or closing it right off. The mixture screw on the ECU has been tried in various positions but I have left it in the middle until I can get the idle up to 850RPM on a hot day.
Any suggestions?

BTW I have been to Kjell's D Jet page but it hasn't helped.
Full Version: Hot day and idles too low
Numbers should be 15-1600 or so, settling to 950-1000.
Drive car til hot. Disable AAR by taping over FEED end of tube from AIRBOX.. disco that hose, and tape it.
Set idle screw for 950-1000.
Check that idle doesn't hunt. *(vac leaks suspected after ECU knob has been set to the indent, and turned clockwise a few clicks, without change)
If idle is good, and not hunting, remove tape from hose, and reinstall.
If you reinstall AAR hose, and idle goes up, your AAR is failing open (doesn't sound likely.. you seem to not hit idle with screw all the way out?)
What are your engine temps? You could be hot hot.
Does your flapper have a hole drilled in it?
