Go down to Pep Boys and buy a compression gauge. Warm the car up to normal operating temp. Remove the spark plug wires then remove the spark plugs. On the driver side firewall there will be two relays, uplug both of those. Screw the gauge into the spark plug threads have a buddy turn the car over, when the gauge needle inside the gauge stops moving that is your compression for the cylinder. Repeat for the rest of the cylinders.
