I suspect a fuel delivery problem. Run a couple of tanks of gas with a good fuel system cleaner like Seafoam or Chevron Techron concentrate.
Thanks guys for responses will get scan and will let you know Thank You very much .
Make sure you don't have any vacuum leaks around the PCV valve too. If it looks plugged replace the PCV valve.
Hi guys car still sputtering does it when it's cold or hot like I said changed wires plugs crank sensor, cam sensor, vss, coils, module, could it be fuel pump?
Check your idle control valve
