My idle is acting up, it bounces up and down from around 1200rpm to about 1500rpm, just bouncing back and foreward. I suspected a vacuum leak but I've replaced all lines with new ones and rechecked my lines from the FSM. I did notice I didn't have my IAC plugged in, but today when I found it, I plugged it in and it still did the same thing.

After awhile, apparently when it warms up, it stops doing it so much and holds idle pretty good.

Before the rebuild there was no idle issues.

My ECU is throwing code 14 though which is IAC. I even tried resetting the ECU.

If anyone has suggestions, that'd be great.
