Bad Stepper motors....the motors in your cluster are very weak... there is an upgraded motor x 25-168...cost 175.00 parts and labor to replace all of them. Ive repaired a lot of clusters with this very problem

Hi, this is being caused by a malfunctioning sending unit that is locate inside of the tank and is part of the fuel pump assembly. replacing the sending unit will fix this issue.

Please rate and god bless:)

Check your coolant level. If you have air in the lines, the times when there's no coolant in the area of the sensor will make the temp go up rapidly, then it goes back down when coolant hits it again. You need to get the air out of the system, or you WILL have larger issues at hand, like a blown head gasket, cracked head, reduced piston ring sealing, or material transfer from the pistons to the cylinder walls. One other thing that could cause this is a faulty thermostat.
