1988 Chevy Silverado timing check

Bad miss in the Silverado, checking codes and timing

Gotta love ODB-1. Gotta unplug the wire under passenger dash and set timing to 0 degrees. On most of the tbi trucks. Gotta plug wire back In before driving or it will run bad. Yeah you got to what I was saying lol

Umbrella seals with repair always good and cheap.
