When you install a new IAC do you just put it in and the PCM picks up the position of the pintle, or do you have to set the pintle in a certain position beforehand?

 

just plug it in and go.

 

When installing a new IAC, you may move the pintle to match the measurement of the old one. The force required to move a NEW valve will not cause damage to it. Use engine oil to lubricate the o-ring. Tighten attaching screws to 27 lb. in.

 

Thank you.
