Mass AIR Sensor problems

When my Mass air flow sensor is plugged in my car idles irregular. When i press the gas pedal the car jumps as if im pressing the gas and immediatly letting go. When i unplug the air flow sensor it drives fine. But my Check engine light is on. I took it to a mechanic to look at my car. They replaced the sensor and it didnt fix the problem, i even replaced the ECU. Still didnt fix anything. Could i possibly be the O2 sensor?? WHat else could it possibly be??

If it runs fine with it unplugged then I would drive with it unplugged. The cheap solution. lol :2cents:

Now if you wanna do it properly, then I would unplug it so the Check Engine Light comes on and then have Autozone or somebody scan it for you to determine what else is wrong with it.

Is it turbo or non turbo?
