The #2 power bank has the largest problem from cylinders 2 and 4. The direct test results point almost directly to bad cylinder head gasket(s) before the math is even finished. Another obvious way to verify bad head gaskets is to check for coolant in the oil as well as the white smoke coming from one or both exhaust outlets. Normally that points directly to the problem before anything else. This test is the final nail in the coffin for a flawless diagnosis of any and all of the symptoms. Excellent job and video!!!!
Very well done 👍, sort of reminds me of a relative compression test , it’s dirty free tests that saves you time and gives you a track of where the problem is, especially it looks like 2 of the cylinders are low compression, good job!!!👍👍👍
One other thing to note is that cyl’s 2 and 4 are adjacent and on the same side of the engine. This also helps validate a possible head gasket issue as a blown head gasket usually affects more than one cyl but only on the same side of the engine. We would also expect the condition to affect cylinders that were beside each other. Your data confirms this. Thanks for the video!
You should have to disconnect the IAC Valve to avoid the compensation of ECM/PCM during and after of each test, in my opinion you can work just with the minimum of each cylinder to find the cylinder with less contribution

Isn't it cyl 1 and 4?
Excellent video lesson!!!
snap on is very limited for supported models very frustrating

Wouldnt 2 and 4 be next to each other?
