Just got my truck back from the body shop. Took it out for a drive and my EGT gauge is reading 600* at an idle and goes up to 1000* degrees during casual driving around town. The temp goes up with the RPMs, the gauge lights up and functions. Its the PPE gauge with the original probe, which is a couple years old now. I think its the probe, but i am open to other ideas to check out. Thanks.
