Question about 1989 Volvo 740
Check the connectors to the temperaure sensor, I think it has been crossed with the knock sensor. I had an earlier model volvo with same problem it was like that since I bought it. I found out somebody crossed the temperature sensor with the knock sensor. It took me a while to figure it out. I had to use an schematic diagram.
