2.4L, 4 cyl. when my car idles or at any point in time it starts to skip. i don't know if it is losing pressure or what. we changed the plugs and not too long ago changed the plug wires, egr, and the pcv. i think thats what its called. anyone have any clue what it might be? Any ideas would be very helpful. thanks alot.

 

might be something like a fuel pump, fuel filter, or something else in the fuel system. have that checked once. i had a car that did that once upon a time and i had to replace fuel filter and pump.

 

Try a fuel system cleaner. Check fuel pressure at the rail. Look at the plugs and see if any of the cylinders are running lean. Check for codes.
