Keep these videos coming . I want to build a solid foundation to diagnose issues . Getting data from the scan tool FIRST before loading the parts cannon . Knowing what to look for from each sensor and what the data is telling you . Thanks .

Nice video. Just wanted to add a comment for cars that use a MAP sensor instead of a MAF sensor. Vacuum leaks on MAP controlled vehicles will not be visible in the fuel trims.

Air Conditioning would be a good video! I just barely scraped by passing the A7 and I certainly could use some reinforcement.

This channel is awesome thank you so much Im trying to get into the diag side of auto repair and these vids are absolutely priceless gems. Simple, straightforward & practical.

If I was going to teach a vacuum leak AKA false air leak, I would want to show MAF readings also with this very small leak and a larger leak since you were able to control the size so I could monitor MAF small leak and larger leak and after the repair and since I am teaching MAF I would also have waited for a problem in a vehicle with a dirty MAF then done cleaning after fixing the leak to show more MAF readings based on these 2 scenarios. This is why creating a problem is not always a real-world scenario but THANK YOU for this beginner lesson that is in fact a useful lesson for a vacuum leak ONLY on any car that you did mention.

P0171 fuel system lean can also be Maf and fuel system issues. Dirty fuel pump or injectors. Had one recently with dirty injectors and wondering why the LTFT wasn't dropping after the repairs. Now I know that I have to cycle the key off. Thanks.Always great diagnosing from you guys
