Gas gage moves from time to time speedometer doesn't work and temperature gauge goes up but doesn't overheat? New thermostat, new water pump, everything. have new speed sensors to install but don't want to waste time if it is more then that.

More then likely this is a cluster issue and not the individual sensors. Clearly this could be the sensors if each of them failed one at a time but if they are all not working at about the same time then the printed circuit board on the cluster has failed.

Here is the wiring diagram if you would like to check voltage coming from the sensors. I suspect you will find constant/steady voltage from the coolant temperature sensor when the gauge is ranging. If that is the case then that means the cluster is the issue.
