....reaching running temp the idle varies between 1400~1500 RPM. That's backwards from what it should be? I have replaced several hoses, checked all areas I could with spritzes of carb cleaner without any effect, so what other components regulate RPM at temperature? I'm no mechanic with the finer details of the D-jet system on my 1.7L motor.

Engine wants more air at cold start up. This is the job of the AAR. So if you adjust your idle back to 950-1000 when warm your car will probably not idle when cold.
Air leaks are sometimes hard to find. Start by checking the AAR and work your way through the entire system Worn throttle bodies can cause issues as well and are often overlooked. I spent a long time with my L-Jet air leaks to make it happy... |
