compression test
1st unplug plugwires and remove the plugs.Then disable your ignition by removing a 10 amp ecm fuse located in the engine compartment fuse block.Screw compression tester into plug hole snug crank engine over 5 revolution and look at your reading go on to next one.spec should between 190 to 220 for healthy engine hope this help
one more thing, and very important.
if you want accurate readings you must have the car up to running temp. so drive it around for 10 minutes and then do it
whats 5 revolution mean? so i take a plugs out at once? do i need a friend or can i do this myself?

NO you dont need a friend.Remove all the plugs and screw in your gauge crank the engine over for about 10 seconds then go check your gauge reading and move to the next one
the throttle has to be wide open, right?
yes
