Vacuume Leaks can cause this problems. you have to do a through check of vacuum hoses and the EGR valve. Your best bet can be to have your vehicle scanned at an autozone store and get a code. The EGR has to be closed at idle, then as the engine warms up or is accelerated, the EGR opens. That is if your car does not have an electronic EGR . The electronic EGRs do not use vacuum to operate. They are controlled by the PCM (power train control Module).

Could be a short in the wiring for the O2 sensor. I currently have the same issue only my car finally threw a code after two days of it acting up. Code 106. Changed the MAP sensor and it now throws 108, MAP sensor high voltage circuit. Ah the joys of cold weather and broke down vehicles. But I know that you wont always get a code with a short. Let me know if you fixed the problem.
