I removed all the plugs and did the test again. Once again I still don't trust the testers accuracy + my inexperience, but the results are still telling right?
1-3 no compression
4 jumped to maybe 40
5 pumped up to 55 maybe
6 35-40
7 maybe 15.
8 the hose was too long in this test for me to get it to screw in.
I will try this test again with a proven tester and with a little more care, but obviously things are off. I have a video uploaded to show the results and how the engine idles. The first 10 seconds show the plugs (bank one clean, bank 2 every plug was dirty) the next 30 seconds show my test and the last little bit shows the engine at idle when I first picked it up. I've since had it higher like I explained in my original post. Anyway any pointers from here would be most welcome.
