My car acts like its not getting gas. When at idel it will sometimes hang at 1,500 rpm then it will drop to 500 and cut off. When I'm going up a hill it will just skip and rpm will go from 2k to 500k then back like three or four times then it will be ok. I had a code for a mass air flow sensor and I replaced it but still doing same thing. It only seems to doing it going up hill! on wide open throttle is will hesitate some then it goes just fine. No loss of HP. Anyone have any ideas?

Possible bad O2 sensor. Even if it is not throwing codes. Do you have any spares you can swap in to test the theory?

I will try that today! I'll have to buy one or two but at this point that would be cheaper than i thought.
