We had the same prob.
Changed the sensor and still no luck. It ended up being the CamShaft position sensor magnet had broken off and fell into the oil pan.
Because of this the timing chain and gear set had to be replaced as well plus oil, and antifreeze. it runs fine now.
Hope this helps.

stegerohio; I am pleased to see this "cam gear magnet" problem mentioned once again. It is more common than most people will admit!! Glad to see it fixed your car also.
