2004 Silverado, extended cab, Z-71, 5.3 Liter engine.
On the way home last night I noticed my speedo was reading 65 mph. I didn't feel that I was going that fast. Took my foot off the pedal and as it slowed down the needle stayed at 65. Got home and turned it off and it still reads 65 mph. Any ideas? Had a problem several months ago with my oil pressure guage and found out it was the sensor thanks to this site. Thanks guys/gals.
