    When my car is idling it seems to sputter really low in RPMs almost as if the engine is going to die. I give it a little gas to keep the RPMs up then its fine, it never used to do this until recently though.

    What could be the problem? Common stuff?

    You can try using throttle body & air intake cleaner on the IAC, IAC hole, and throttle plate. DO NOT use carb cleaner.

    A massive vaccum leak or bad PCV valve can cause this issue as well. Even a dirty air filter won't help and could be the cause if you have also noticed a loss in MPG.

    it could be a clogged intake or something to do with the timing. my car did the same thing and shot out codes telling me my camshaft position timing was over retarded and the camshaft position sensor was malfunctioning.
    hope that helped. hope ya find your problem.

    I had the exact same problem. The vacuum line had a slit/tear in it. I could see it expand and contract as I revved the engine. A quick fix was some duct tape but it was easily replaced with the correct replacement part.

    Hope this helps.

    thank you for all your help and answers :)

    for all who said vac leak... you were right!! The IAC was fine just a crack in the vac hose. Got it replaced and now it works fine again!!

    this exact thing happens to me. please keep in mind i know next to nothing about cars. the check engine light is on. i took it to o'reillys so they could tell me what was up. the plug in thing said "bad o2 sensor"

    could this be whats doing it? and also, theres 2 o2 sensors if im not mistaken. one before and one after the cat. which one would be more likely bad and need to be replaced??

    In the code, it should tell the location of the sensor. For example: "Bank 1, Sensor 1" would be the front O2 sensor. Bank 1 is the set of cylinders on the engine containing cylinder 1. Since our cars only have one bank of cylinders, you should never see "Bank 2" on this car. The sensor location is given a number based on where it is located around the catalyic converter. "Sensor 1" is before the cat, and "Sensor 2" is behind the cat.

    Do you happen to have the actual code number? Sometimes the problem is not the O2 sensor, but either the wiring to the sensor, or some engine problem causing the O2 sensor to read wrong.

    I had a bad o2 in bank 1. It was causing the same symptoms. My code was p1131. I went to change the bad o2 sensor and also found a slightly cracked manifold (common for the zx2, the crack is usually between the #1 and 2 cylinder). Take it to your local parts shop to have them run the code and see what it is. Its also beneficial to see if that manifold is cracked or not, it would cause a lean reading as it pulls more air in thru there, which in turn, might rule out a bad o2 sensor. My car was due for a new one though so im glad i changed mine.
