Classic Chevy Christmas! - Part 2: Emissions Systems

Well let's start with some basic checks on the Oxygen Sensor and Emissions devices on this Classic Chevy that could be affecting idle quality.

In cases like this, where EVERYTHING is a variable, we must check EVERY system of the engine controls, one at a time!
Will we get lucky, or is this just the tip of the iceberg?

Enjoy!
