Temp and Oil Gauges - slow to wake up.
The water temp and oil pressure gauges on my '99 4.0 don't work when I first start her up in the morning. The needles are at rest on the bottom pin. After a mile or two, they start flicking between the at-rest pin and a "normal" reading for several seconds, making a clicking sound, and then they begin to work normally. The speedo, gas and voltage gauges are all fine. Does this indicate a problem with my cluster?
