check engine light coming of and on help !!!

Sitting with the car idle or running down the road the car jerks everyonce in awhile. When that happens it throws the 311 and 314 codes which is o2 sensors codes but the goes away a few minutes later. The sensor are a year old. Whatever its doing its throwing my tps sensor off on the volts to .9 volts at idle and not reaching no more that 1.6 volts at full throttle. Replaced tps sensor and still does the same. Fuel pressure is at the low at 30psi. Can anybody shed some light on my madness any help or tips would be greatly appreciated.

The smog was removed several years ago. As for the tps its new as stated before. Both were showing .9 volts at idle and 1.6 at full throttle. Cleaned the mass air acouple of weeks ago. Only thing i havent cleaned is the IAC. Thinking about even looking at the fuel pump. My wifes jeep was doing similar throwing a
o2 code and i replaced the fuel pump. When i bought the car ive had to replace the fuel filter several times due to trash in the tank. Any suggestions would be great thanks.

I dont no if this has anything to do with it also. But when i cranked it up earlier when you rev it up its making a whistling noise like a cold air kit sound.
