Any ideas?

MAF sensor, or something simple as a bad ignition coil/ coils.

My car had the same symptoms in a addition to pinging on hard acceleration. I purchased a OEM Denso MAF from Rock Auto. End of problem. Car rides like a new car. Make sure you disconnect the battery for about 30 minutes before installing the sensor. Good luck.
