My 2005 Tahoe's gauge jumped to 80 as soon as you turned the key to the on position and stayed at that level even after the engine started. This is a common problem with the 5.3 liter engine in cars from 2000 to 2006. These sensors are to blame 90% of the time. Luckily, this is a relatively easy fix that you can accomplish in your driveway at the expense of the cost of a part, a deep well, and a swivel outlet extender (if you don't already have the tools). Works as it should and delivered quickly thanks to Revain Prime!
