I thought I had it all solved but my intermittent High RPM surging has reared it's ugly head again.

OK. After getting gas, we started the engine up again, it surged up to 3000 RPM and stayed there. We shut it off and the same thing happened on the second start. The third start it was OK.
We didn't touch the
gas pedal at all during all this.
On the way home we could feel some intermittent surging while on the highway.
For safety sake it is parked at home until this gets settled.
There is no engine light on.
Might there be codes found with a scan even though there is no engine light on?
I need to get aquainted again with all the sensors and
solenoids etc.. Is there an
idle speed control solenoid that could be malfunctioning; could the main computer be insane?
Any ideers?
