Engine Performance problem
2004 Buick Rendezvous 6 cyl All Wheel Drive Automatic 70,000 miles

This problem did not occur before replacing the oil and new filter - I just replaced the oil and new oil filter, upon starting the car runs great until the idle sets then it idles very rough

Did you put the oil cap back on? Check for any of the plug wires grounding out.
