1990 Toyota pickup 22RE smog emission system overview w/ EGR, Air Injection & EVAP charcoal canister

This video details how the three major emission systems of the 22RE function on my 1990 Toyota Pickup truck. I learned the most about how these systems are laid out by going through the factory service manual, so I thought I would make a video showing sort of the same method I used in order to better understand how everything works and what does what and/or which hoses go where, etc. I hope this video helps out anyone who is trying to better understand everything which is happening while the 22RE is working to control emissions.
