Check your rad hoses. They will tend to collapse (**** in) & cut down on flow at highway speeds, more than city, due to increased demand & flow on cooling system. If they don't feel relatively stiff, I'd change them. You might even see them **** in while sitting and revving the engine a bit.

your code could be either a intermittent signal from the cam or crank sensor.
