LH 2.4 error code 123: I can't get rid of it 200 1993

I actually didn't check the ezk this time but I have never got a code from the ezk in the past.

Thanks for the info on the limp mode. At least the car should get reasonable fuel economy when the light is on. It does not make sense that it is a ground problem because I am getting low resistance not high.

I am starting to think its not the temp sensor, but another warped head that is starved for coolant around the temp sensor. I drove it today on short trips and the light stayed off. It seems to only happen after a long highway drive on hot days. There are other signs of a warped head. Oil is leaking out and I don't think it is the valve cover. It also runs a little bit rough when it is cold but smooths out as it heats up. No white cloud of smoke when you start it, like the last one, but I suspect I will start to see that this winter when it gets colder.

I'm not sure what I am going to do. I don't know if it worth putting another head on this engine. I am thinking it might be better in the long run to put in a good used motor rather than keep messing with this one.
