I have had a diagnostic done since my SES light lit up, it appears that cylinder #3 is only getting 90 psi compression while the other 3 cylinders are at 120 psi, any idea why this is happening?

My car's mileage is not very good, it "kicks" or "buckles" while accelerating and idling is rough and "jumpy".

Tanx in advance for your help.
