Try ACDELCO 19160423 as an example.Belgian1979 wrote: ↑Sun Mar 11, 2018 2:27 pmThis certainly is a possibility, but I never found a stepper motor powerfull enough to work against the springs and such. Do you have a part number ?peejay wrote: ↑Sun Mar 11, 2018 12:44 pmIt would be far easier to use an IAC motor that opened the throttle directly, for various reasons related to the strangeness of IR setups. 1980s Cadillacs with the 4.1/4.5/4.9l engine used a stepper motor throttle stop for idle control that would serve you well.Belgian1979 wrote: ↑Sun Mar 11, 2018 3:53 am
iac air to individual runners that I need to get balanced. The full details would mean a very very long explanation....
Note that this is a stepper motor, and requires specific circuitry to control. I believe it works the same as GM's air valve type IACs.
