Analog temp signal to dash

The engine started right up and we checked the coolant. Then a couple of things happened. The analog gauge did not work and the service engine soon light came on. The digital temp was only reading 203 degrees at the time. There could be one or two items for that but I checked the codes before and nothing came up. He wants to put new plug wires in which is okay by me but time consuming. The Z hasn't had a lot of attention in the past five years so these things keep cropping up. The car is a 92 and a dark red color of which only 17 were made. It has multiple issues with clutch, brakes, headlight motors, etc.

Well, Good you could be of assistance. The Brotherhood is the best source of assistance to keep these babies in top shape. Good luck!!

Well, the analog gauge doesn't work and I suspect that it became disconnected somehow. The codes show a H44 in the ECM which is a left O2 sensor fault. Started up the car and no service engine soon light on and the fan came on at 227 degrees. Took it out for a spin and the brakes started getting real hot. When we brought it back to the house, Carlos said that it acted like the emergency brake on on. Both the calipers on both front brakes were smoking as well as the brake pads. Got a small amount of coolant laying under the injector housing. Fix the analog gauge, put in new plug wires and check the underside of the plenum and see if we can locate the leakage.
