ok, so I tried searching (the search tool is a bitch here) but I seem to remember reading somewhere on here someone mentioning that the haynes manual had the directions for adjusting the idle knob on the ECU for a D-jet was backwards.
I just finally got some nasty vacuum leaks fixed and now I can adjust the idle all I want (YAY!) but it seems to be running rich and I don't want to make it worse. I can smell the raw fuel in the exhaust, and I know that I have exhaust leaks but since I fixed the vacuum leaks it's popping 3-4 times as much now especially on downshifts. |

why do you want or need a potentiometer to adjust idle? If you are putting it inline with the CHTS that will adjust the mixture at startup but once the motor reaches operating temp. the CHTS is ignored. The biggest misconception is that the CHTS is used throughout all temp ranges and is a integral part of idle adjustment all the time.
If the CHTS where bad and going in and out of range this would make the car run rich becaouse the ECU thinks the motor is cold. A potentiometer would be good to have to be able to sync. CHTS enrichment with the AAR. There should be a idle adjustment knob on the ECU. How is your fuel pressure? Have you checked the MPS? |
