97 F150 4.6 4X4 Manual transmission. This has me frustrated as hell. First off this is completely random, cold, hot, night, day, just any ol time it wants to. Temp guage needle is jumping up and down, occasionally pegs hot for a second then goes nuts again. When it does peg out hot or in the upper range of the guage, the “low oil pressure high temp light flickers. This is the indicator in the left upper area of the cluster. Now I will say it’s a 50/50 shot when you drive it that it actually acts right and the guage is correct. What I’ve done so far. Changed both sensor/ switches on right hand side of intake, had oil pressure checked, checked anti freeze amount, made sure thermostat was opening. Took it to the ford house and they said it needs a cluster. Bought a reman cluster and didn’t fix the issue. Any suggestions?
