well heres what i know so far for a compression test:
pull ecu fuse
take out ALL spark plugs at once and check each cylinder
turn key to crank over 4 times on each cylinder.
would i have to hit the gas pedal at all? thats what somone said

this is what ive gotten out of the search so far. i know i dont have everything down so please help so i can do this right

 

yes you should hold the throttle wide open while turning the engine over.

Keep cranking until the gauge isn't increasing any more. 4 is about right, but that's not an absolute rule.

 

I concur.

 

Also make sure your car is at operating temp b4 you do the test...dont want to be doing 20-25 cold cranks

 

Just don't use the piece of junk compression tester for $15 from Harbor Freight. I regret buying it... not only does it fail to work correctly (doesn't seem to tighten to the spark plug hole enough, so you lose a ton of pressure when doing the test), but the adapter piece got stuck down in the spark plug hole once... had to buy some loooooooooooonnnnnggggg needle nose pliers to get it out. Luckily I didn't tighten it that much or else I don't know what I would have done (the socket that fits it doesn't fit the spark plug hole). The one from Schucks with the steel braided hose looks nice.

Anyways... yeah... enough of that. What everyone else said is pretty much all there is to it...

 

thanx guys. i was told that i need to regap the plugs after the test. is this necissary? there boschx4's. they come pre-gapped. does this have to be done to spec again?

Might as well check when they are out.

Bosch Pt+4 have a strange gap, cause they use some kind of surface-arc. I don't know if the gap is supposed to be the same as normal plugs. Besides, the center electrode has that ceramic collar around it, so its hard to measure the real gap...
