O2 sensor failure on a Holley Sniper EFI
Attempted to make a parts run in my 1990 Third gen Chevy Camaro with a small block chevy 350 with flowmaster mufflers. I believed the issue in this video to be a bad O2 sensor however In the next few videos I come to find its actually a bad ECU in my Holley Sniper EFI.
