Sometimes my temp guage is working then goes to zero, after a little while it starts working again, any thoughts, thanks Jim.

If your fuel gage gets erratic at the same time, suspect the cluster Vreg. Yours is inside your fuel gage. If so, replace it with an electronic one. Search "Plymouth voltage limiter" on ebay or search "IVR" here. Could also be erratic connections to your sensor. Many, many posts on this, so search.

If only the temp gauge comes and goes, its most likely just loose contacts to the circuit board. Limiter fault would fault all the thermal gauges.
