compression test

[PynkEye]

Ok, tomorrow ill be checking out my compression.
Need some pointers.

Heat up the car, wait 10 min to cool down, then take out the EFI fuse so no gaz goes there.
Do I take out all the spark plugs ??? or one at a time.
Do I need to unplug the coil pack ??? and how.

Any pointers on how to do the job right or links would be great.

Thanks

Pull all the plugs

either hold the throttle down when cranking or wire it open

If you don't unplg the coils make sure none of the leads are near you while cranking

Remove all the plugs

have a booster battery handy in case the voltage drops
