I've read through all of the fast idle pages, and none of them seem to have the same problem as me.
First of all, when i start my car, and the engine is cold, the idle will jump up to about 2000rpms, and over the next minute, it will climb up to about 2500rpms. It stays there and is very steady. It will eventually go down to about 2200 to 2300rpms after the car has fully warmed up. No surging or anything that seems to be associated with the FIAV or the ISC.
Another thing, i adjusted my BISS all the way in, and thats how i got the idle THIS LOW. Which isnt low at all...
This next part pertains to the next question:
I'm only running 1 fan on my radiator, because of my 16g install kit, and so, earlier this summer, when it was still hot outside, i could let my car sit and idle (high) and as it began to "heat up" above 220 and between 235 the idle would go down as it heated up. But it never got below 1800 rpms, and that was when the engine temp was at 235. I never let it go above that...
SO, my question on this is, if it was a vac leak, would it change like that?
Another note, when i adjusted my BISS, i just hooked my palm logger up to it, and turned the screw in. The idle followed accordingly, but never dropped to "normal." Is that the correct way to do it? I know the VFAQ says to center the ISC, but i don't have a way to do that. Do i have to pay a shop to do it?
Thanks
