Duke you know what I forgot to tell my helping hand (wife) was to press the gas pedal to the floor, oh my, oh well. What effect does this have on my compression test?
Welllllll... it might make the cylinder to cylinder readings a little more inconsistent than they would be with the throttle wide open so there is no restriction to air flow.
I think not blocking the throttle open for a compression test is a common error.
