1997 Silverado 5.7 tachometer reading double.
1997 Chevy 3500 5.7 I'm racking my brain at what would cause this truck to read ruffly double the rpm it's actually running at. CPU is seeing it properly when I look at my scan tool.
No modifications, just replaced the heads. Any tips would be much appreciated.
