Troubleshooting guide the air intake button automatically be off.

Engine idle speed is limited by reducing the amount of air entering the engine. When an accelerator pedal is pressed, it pulls a cable which opens a throttle plate which then allows more air to enter causing engine RPMs to increase. At an idle, the throttle plate should be closed as to not increase the RPM. There's also a part called the idle air control (IAC) valve which controls how much air bypasses the closed throttle plate at an idle. Lastly, air could enter the engine via an intake gasket or vacuum hose leak; the same rules apply, the split hose or gasket allows air to enter the engine and RPMs will rise. To summarize, a throttle plate not closing, and IAC valve stuck open, or a split intake gasket or vacuum hose could all cause a higher than normal idle condition.

Fern, I believe you mean the Mass Air Flow sensor (MAF). It is normally found in the fresh air intake plastic/rubber hoses attached to the air filter box, on yours it may be in the part of air filter box. Check the attached links,instruction and guides, Good luck

If your car has a MAF sensor, it is in the air intake hose between the intake and the air filter.
If the check engine light is on, you would need a scanner to read the computer data coming from the sensors to diagnose the problem.

DISCONNECT THE ELECTRICAL CONNECTOR FROM THE INTAKE AIR TEMPERATURE SENSOR.LOOSEN THE HOSE CLAMPS THAT SECURE THE AIR INTAKE DUCT TO THE AIR FILTER HOUSING COVER AND THE THROTTLE BODY,THEN REMOVE THE AIR INTAKE DUCT.REMOVE THE AIR INTAKE DUCT AND REMOVE THE AIR FILTER HOUSING MOUNTING BOLT.DETACH THE AIR FILTER HOUSING ASSEMBLY SIMPLY PULL IT UP AND DISENGAGE THE TWO GROMMETS ON THE UNDERSIDE OF THE HOUSING FROM THEIR GUIDE PINS ON THE VECHICLE.PUT EVERY THING BACK VISA VERSA. IF HELPS TAKE NOTES AS YOU DO IT.WHEN FINISH YOUR NOTES WILL GUIDE YOU TO FINISHING YOUR REPAIR.

make sure that your clean air intake is all hooked up correctly this is a common problem because when the mass air flow sensor detects too much or too little air it will try to die or idle rocky also if it is correct look to make sure the air filter is clean if not then replace it.

Have you checked the transmission fluid? Sometimes if the transmission is slipping that bad it is really low on fluid.

BAD PLUGS AND WIRES+COIL. DIRTY AIR FILTER.AUTOMATIC TRANSMISSION CHECK FOR LOW FLUID.IF YOU GOT MANUAL TRANSMISSION CLUTCH SLIPPING.FUEL FILTER STOPPED UP.AIR LEAK AT INTAKE PLENUM OR AIR INTAKE DUCT AT THROTTLE BODY.
