how do you check the compression?
I have a 94 I6 and want to see if I can do it, with little skills or should I take it some where?
Also what should they be?

TIA

buy a compression gauge. about $ 20


pull the center wire from the distributer off so the engin doesn run

take out one spark plug, screw in the compression gauge, have a friend turn the engin over a few times while you watch the gauge bouce around get your reading. replace spark plug and move on to the next.


should be over 125 at least
