ford pwm iac
I am trying to set up a ford pwm valve for idle air control. my question is when the engine reaches operating temp should the valve be compleatly closed, or does a small amount of air always pass through the valve. I have changed the pwm numbers but cant seem to fully close the valve.

Re: ford pwm iac
droptop,
If you have the IAC value set to 100 at the engine's "operating" temp than it should be closed. I bought a new IAC and before installing it tried blowing through the passage -it was closed. Crap builds up on the sealing surface of these (mine sees the oil vapor from the valve cover) and the pintle sticks.

Re: ford pwm iac
When I remove the motor the valve closes. but with the motor conected and the 160 degree value at 100 percent. there is still a small bit of air getting through. Is there an adjustment im missing frequency or another?
