Just a question or two about the dash guages....When I start up my truck, the oil pressure guage just starts spinning....after the truck warms up, the oil guage still spins and the temp guage barely moves off of the bottom notch. Meanwhile, the volt guage reads about what I would expect it to read. I have replaced the tstat because I thought that might be the problem but it didnt change the symptoms....I have also looked at replacing the circuit board in the instrument panel as well....any suggestions? I havent replaced the oil pressure sensor yet but figured I would wait becaue the problems all seem related to each other. Also, my gas guage works sometimes and sometimes it doesnt. I havent replaced the sending unit yet again because it seems like all the problems are related.
