I have a Auto Meter Ultra Lite pyro gauge and since yesterday the gauge is all over the place. It will read a max of 800°f but getting there or any throttle input will cause the needle to jump around like crazy. I went out and bought a gauge and probe kit to replace either part. Before I take apart my 3 gauge mount(stupid me not leaving enough extra wire when I first installed them), or crawl under my truck in -12° to replace the probe, I was hoping for some input?
What do you all think it would be. Probe or Gauge that is no good? Hoping the probe then I will have another gauge to install for the egt on the right side of the truck when it warms up.
