The codes say that 1, 2 and 3 were not contributing during the test. What scanner were you using? How many times did you run the CCT? I've ran it back to back a number of times with AE and had it fail on 2, 3 or 4 different cylinders each time and even failed on all 8 once. Did you notice what your EOT was? There is a minimum required to run the test but I've found that when temps are near the minimum it will fail cylinders but if it's closer to 200* they all pass.

definitely sounds like the scangauge is not very reliable with this test

Its not the Scanguage its the test in general. No matter what scan tool you use it could have that issue.
