engine cyl compression loses as it warms
Number 6 cylinder loses compression after it warms. Cylinder reads 330 psi cold but ran it thinking it was a injector so new inj is installed and vibration returns I go back and do a warm compression test and now I'm getting 270/280 psi.
anybody want to chime in

Warmer air is "thinner", so it would drop some in all cylinders because of that. The IC is there to help prevent the thinning of the air, but the IC doesn't come into play in a compression test.
