Also, you have to be very careful on how you do the compression test. Be sure your battery is fully charged before and during the procedure of testing all 6 cylinders.

Count the number of cranks for each test to be sure you have the same for each cylinder.

Be sure your throttle body is fully opened when doing this test.
