many times
So the car seems to be running good but I cant for the life of me get my ISC within the 30 range and get the airflowperrev anywhere close to 25
I am running DKS 280 cams so ive tried with an idle of 1000 and 950 and I think it runs better with an idle of 1000.
Ive tried turning the biss screw to get the ISC to the 30 range but it will drop down then slowly raise up again. If I turn it too much the car wants to die and thats when I turn it back up. My idle is pretty decent and my fuel trims are in check, but I cant seem to find the happy point for the ISC.
I also pulled the plug on the ISC to check the ohms from 1-2, 2-3, 3-4, 5-6 and they all were within spec
Also ive tried to log the airflowperrev in the sd ve table and drop the cell 20 points and it lowers it a little bit but then idles really bad and the fuel trims are in the 20% instead of 1-5%. But even with that drop in the cell its still in the 40 range for the AFPR.
Any advice would be greatly appreciated.
Thanks
