I have heard that you need to remove all the plugs at once to do an accurate compression test. That would be a lot of work all at one time. They suck to pull and replace. If i did them one at a time will it still give me some idea of the engines condition? Like when i replace the plugs i did it one at a time and that way if it got tired or feed up i could wait to finish and still drive the car in the mean time.

 

Like the guide on my site says, removing all the plugs is the correct way to do it.
