Those readings sound unbelievably low, especially for a
recently-running car. I'm also particularly suspicious of all four
reading being so uniformly low. Did you have a good seal with the
compression gauge? Is it the type that screws into the spark plug
hole, or do you have to hold it tight against the opening by hand?
Did you have the throttle wide open when you cranked the engine?
That can make a big difference. Heck, with numbers THAT low, I'd
even begin to suspect the gauge. Have you tried it on another
vehicle?
