I changed my oil / filter / pcv valve / spark plugs
afer that It ran rough like a studder while you drive, in park it idled ok, (the car had no problems until I did the above)
at that point I went ahead and replaced the spark plug wires, still has running rough.
I pulled every spark plug and check for cracks and check order of spark plug wires, ok is ok, still runs rough

I would guess a vacuum hose is off somewhere near the pcv valve but I dont see any loose or off.

any ideas?

btw car is a 2.8 L. V 6 has only 65000 orignal engine

Thanks
