My '82 308 GTSi is having trouble with the water temp guage and the oil pressure guage. The water temp guage is never consistent, somtimes it will work, (however I beleive it to be reading a bit low), sometimes, it will flicker between nothing and the temp it is trying to read, and other times it will just not work at all. It does seem that if it is not working at all and you wind the car out through some gears it will want to come back to life a little, maybe, but I am not sure. The oil temp guage usualy give me a good a true reading, but sometimes this guage will flicker and die. What causes this? Bad guages, bad contacts somewhere, sending units? Thouse guages are too important to be messing up. Luckily all other guages are working correctly so far. I appreciate any help any of you may give in tracking this down.
