I've been trying to get my compression numbers per cylinder and it looks like all cylinders read 60 psi. Please help I'm not sure what I'm doing wrong. I unplugged one spark plug at a time, spark plug wires are off and power is disconnected. I opened the throttle as much as I could with a screwdriver or yet still same results. Can it be the compression tester itself that I borrowed from Autozone ?
