Valve timing
iac flucs between 120 and 140 could somethin else be controllin this sensor or is it bad
can the opti control valve timing, my uncle ran a vacuum tester on it and it is leanin towards a late valve timing, would late valve timing cause the car to have an idle at around 500 rpms

The PCM has control over idle speed, and ignition timing, among other things, but not over valve timing.
A vacuum leak is a good bet. That would play havoc with the idle.
