2017 Hyundai Elantra 2L - P0303 cylinder 3 misfire - Be careful of used ECMs! Part 2

See Part 1 for the live diagnosis    • 2017 Hyundai Elantra 2L - P0303 Cylinder 3...   2017 Hyundai Elantra 2L non turbo. Came in for a very intermittent misfire that's been there almost since new. The car has been to the dealership MANY times and had a lot of parts thrown at it. Everytime it came to our shop I could never get it to act up. I must have put 30km on this thing! I was FINALLY able to get it to misfire in Part1 where I do the live diagnosis. In this video I'm going over what I found in Part1 as well as the joys of modern modules and security protocols... This was one of those cases where the diagnosis was the easy part! The information, demonstration and any content contained in this video is for informational purposes only.
