Please help, high idle after restart randomly...???

[WeathermanShawn]

My understanding:
B4205 is ECT vs IAT... if IAT is some value x, then ECT must exceed the y value at x for CL to activate.


What is the question again...?

Joe:

I was respectfully challenging B4205 nomenclature that the x values are IAT. The scale mysteriously matches every ECT scale on EFILive. Why would IAT have any control on Closed-Loop? I was concerned that his B4205 was causing a related problem in his tune. We can address that in another thread in necessary..Thanks..

Officially, the OP's question is why is his Idle hanging at 2200 RPM's in a random fashion?

Thanks for the replies gentlemen. I changed the IAC parked closer to stock & changed some of the idle airflow settings closer to stock & all has been well thus far. Originally, changed the IAC parked settings because it was needed in order to have a stable & accurate idle when the intake, cam & heads were first installed. Maybe they were changed too high. We will see. Have gone a dozen or more heat cycles before it reared it's ugly head, in the past, so, it's too soon to know for sure if the changes have corrected the issue. Although, it's a good sign that reducing the IAC counts a bit haven't negatively effected start up & idle. Thanks again. I appreciate the help.

Glad to hear it.

Let us know how it goes. In the meantime I have started a new Idle thread that may be of interest to you..http://forum.efilive.com/showthread....ips-amp-Tricks

Good luck!
