re

This is very odd, if it's doing an emissions test.
In all cases of emissions testing for as far back as I can remember..
the testing is done on a warm engine,
and you want the engine as warm as you can get it for the test.
Like............don't shut off the engine if waiting in line for an
emissions test.
As warm as you can get it.
and .....I have never heard of testing emissions on a cold engine.
Be nice to see what the warm readings are.

With those numbers he needs to start with compression / leak down test. Then
look for ignition or lean miss fire. Then basic settings such as ignition
timing.
