CYLINDER #3 ONLY 90PSI

2007 Saturn Ion

Engine Performance problem
2007 Saturn Ion 4 cyl Front Wheel Drive Automatic 90,000 miles

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.
