A few eeks ago my car would kind of jerk a little when I accelerated. I checked the sparks plugs and they are fine. We changed the fuel filter and the air filter and didn't seem to make a difference. But later that day it ran fine for about 2 days and now it is worse than ever. The engine is rough sounding and it kind of shakes when ideling. Any ideas, or suggestions?

Check the fuel pressure with a fuel pressure gauge make sure its within specs. Test the throttle position, mass airflow, map sensors, EGR and PCV valves
