It was time to replace the coolant, so I thought why not replace the main hoses at the same time - little did I know...
Now that the manual is gone, we all need to post up stuff like this to help each other out.









































The Hunting symptoms stopped and the CEL went off after a few days. All is working normally again. We did put the rest of the jug of coolant into the expansion tank (about a cup). It must have burped some more air out of the system. We will keep an eye on it, but it should be stable now.
