Nope
pull the sensor off and try just running throttle body and if there is no difference, the sensor is bad. if it will not run or acts up without the sensor, then the sensor is good
Check the Mass Airflow Sensor (MAF Sensor). Either it is dirty or damaged.
On my 2000 Grand Prix 3.8L the symptoms were "when warmed up a little the engine would idle up and down and then stall out, I could not restart the engine until cold" I unplugged the MAF sensor and car would run without stalling. Try this method to test yours.
You don't.
Not normally. Usually it willl cause a high idle and lean condition. Your car needs more fuel to run rich... i.e. MAF Sensor or O2 sensor causing out of whack Fuel trims.
Replace your MAF sensor. The MAF sensor provides part of the air fuel mixture information. When they fail, they throw off your mixture. Installing a new MAF will make your car run like its supposed to. Unplugging it is only good to get you home.
A hole or crack in the tube leading from the MAF sensor over to the throttle body.
the engine will seem to cut out or run really rough
Yes. Most parts stores carry MAF Cleaner in a spray can. If your MAF is grimey, it can cause your engine to run rough, hesitate, etc... MAF Cleaner will help a lot. Just be careful handling the MAF, it's a delicate part.
Some possibilities include: faulty or dirty MAF sensor, fuel pressure regulator, or the torque converer solenoid.
dont work to fired run
while driving the car it warms up and becomes dependant on the maf sensor to run the car properly. when you first start the car it runs on a pre programmed set of parameters independent of sensor data until it gets to operational temperatures on various sensors (drive cycle) restarting your car resets the drive cycle temporarily
