Yea it did make a difference.

I just thought it was unique that unplugging the IACV vacuum would cause the car to run perfect and with it plugged in it runs badly.

I assume there is an issue with the plunger or the electrical of the IACV since I cleaned it out and it made no difference.

I wonder if it stays closed with vacuum and without vacuum stays open?
