Sometimes (a lot) accelerating normally from a stop, the car will stumble. One thing I noticed, when it does stumble my vacuum reading jumps to almost zero. When it does recover, the vacuum goes back to around 8 inches then moves steadily towards zero like it does when it takes off normally. I assume the IAC is opening up to much when it does this. Has anyone experienced this? What could cause it? I unplugged the IAC and the idle stayed high, plugged it in and the idle returned to normal, so I assume it is working. See my sig for my setup. Thanks for the help.
