I am having the same problem. I have replaced the entire ignition system, plugs wires etc. Just put in a new MAP sensor and new fuel filter and does the same thing. Seems to get worse when I am going up hill.

Could possibly be a failing pcm, Just because it had o2 sensor codes does not mean the sensors are bad. A bad pcm can cause a false code.
