High Idle above 3k - Error Code 51

That was it. I found a good bit of coolant in around 2 or 3 plugs. Did as you said and it runs like it did before I dumped coolant all over the top of the motor. Thank you.

My car still runs at 1200 rpm and has always had a high idle since I purchased it. The throttle stop screws are backed off and not doing anything idle related.
Is there a dash pot setting in the shop manual?

Has anyone had a problem with the water being pushed into the coolant overflow tank? This was happening before the HG repair and is still a problem.
Will a high idle do this?
No smoke from exhaust. No water in oil. No fluid on the ground.

Thanks again for the input on the poor running condition.
