Question about 1992 Isuzu Rodeo
It may actually be a coolant temp sensor problem - they do have issues sometimes. I'd replace that before anything else - they're generally inexpensive (in the $20 or less range). If, when you ask for a new one, they ask you which one you want, you need the one for the dash gauge. Some cars have one for the gauge and one for the car's ECU. Your problem is with the one that drives the gauge, so get that one.
