My temp gauge says my car is running hot when it's not and my fuel gauge tells me I have a fuel tank of gas when I have only about 2 or 3 gallons. Am I going to have to replace the whole instrument cluster or are the 2 gauges replaceable? Thanks
Sounds like the same problem that plagues the same vintage Kia vehicles.
These cars seem to develop issues with the ground leads, especially the one under the battery tray.
With my 2005 Optima I added 3 additional ground leads that cured my temperature gauge falsely reading high and a strange occasional stutter at low speed.
I added one from the negative battery terminal to the back side of the engine, one from the upper intake manifold to the firewall and one from the alternator to the right shock tower.
Thanks for responding. Got a stupid question: Is it a specific ground kit I need to get? You wouldn't happen to remember the name or have a part number? When I went in to Amazon, it was giving body parts.
I'm sure he's talking about a universal kit like this one.
