My ISC seems to be not working, as in, the ecu doesnt seem to want to change the rpms at all. i can set the idle with the biss to any idle I want and the ecu doesnt try to fight it(try to brong the rpm's to 750)
I changed ISC and put a new black one in, and it didnt do anything, I looked at the ecu to see if there were any burnt spot, it looked fine.
What else is there I can do to make my isc work again!!!
