I've tried to tune idles on couple of evenings and I give up. I have very unstable idle. Often it becomes "hunting idle" and eventually dies, especially coming to a stop. Then another times it is fine.
Sometimes it wants to idle at 0 rpm, IAC drops to 0 too. Sometimes it idles at 0-5* advance, and often at 14*. There is huge lack of knowledge and understanding from my side.
Please take a look at my log. You can see it tries to idle at 138rpm this time. Timing at 14*.
I have 80mm BBK throttle body, 383ci, cam is 227/235 116+6, 3-bar OS, 90lbs injectors.
Please, need some advices...
