Default IAC Maxed out at 145?

I've had trouble with my car stalling at startup lately. My IAC counts never get higher than 145 nomatter how low the idle is. I thought this was max, but I just read 255 is max.

Does this mean replace IAC?

A good way to check would be disconnect the IAC and see if the engine runs any differently. My intuition tells me you need a new IAC or perhpas pullit our and try cleaning it.. it could be carboned up...
