I have watched your videos and I have learned a lot from them. Thank you for all you do. I am an electrical engineer by trade so I know the electrical concepts which allow me to grasp the ideas of workings of sensors, etc. I have one small issue with one term you use: sine wave. I've seen you call several types of varying current signals as sine waves. The term sine wave comes from the term sinusoid and it has a shape like an ac current from an outlet. It has a mathematical expression and used by mathematicians, engineers, etc. There are many other shapes: square, sawtooth, triangle, etc. Many have odd shapes and don't have names. I will give you 5 stars when you stop using the term for non-sinusoidal wave forms. Thank you for your time.

Mr. Paul Danner,

Thank you so much for always putting a 110 percent in everything you teach. It's a pleasure to be apart of your premium online classes and case studies. It's amazing and a privilege to be taught by a person that truly loves and is proud of what they are teaching. It shows in every thing you do. Bless you and your family, have a fantastic thanks giving. !!

You saved my sanity. My son's 2013 ford edge was "misfiring" yet my forscan program kept reporting g ZERO misfires yet my butt knows what a misfire feels like. Lost trust in software and resorted to reacing a coil and moved it thru the front 3 cylinders to no avail. Damn transmission needed fluid change and Voila! Fixed.
Short videos should be called the SS edition like the SS camaro or Chevelle. Could be called super short too. You are just awesome.

Received your book as a gift and I love it. Thank you for all that you do to make the automotive world a better place!!!!!!!!!!!!!!

I hapen to to a UTUBE search on mis-fire on my 2002 ford escape.
I watched your utube video on ignition coils connected wrong. To my greatest excitment, i was watching the exact problem for my vechicle! I could you ten (10) stars if it were possible. I do not have the tools you utilized in your video, and i dont know how to use them at this point, but i am encouraged to press on and now follow your channels and features to learn from your presentations. i commend and thank you very very much. i feel like i was in a college classroom learning from someone who explains and demonstrates in a clear and consice manner. Can i call you "Dr. Scanner?"
