Surging Idle at Startup
Hi guys,
i've got a 2001 F-350 7.3L PSD Turbo, whenever i start it up the rpms go from about 7 or 800 to about 1500 back and forth just reving. untill i tap the gas then this goes away. any ideas on what this is, i thought it might be IAC valve but not really sure.

I know exactly what your talking about. My truck does the same thing but only when it is colder out say 45 degrees and less. It will only do it on initial strat up in the morning and will do it just for a few second. I have seen posts here in the past in regards to this and most say it really doesnt hurt anything. I will also say that I dont have any of this problem if it is plugged in.
