My 1997 Ford Taurus stalls when I accelerate. It only happens about 5 to 10 minutes into my drive. It starts up fine. If I am driving and the car stalls on acceleration, I can turn the car off and back...
Replace first, the fuel filter if this has not already been done. You may have a plugged filter, and these are very inexpensive. If this does not resolve the issue, locate the MAS (mass airflow sensor) located between the throttle body and the air filter housing. Start the car and let it idle normally; with a screwdriver handle or other such small tool, tap the mass airflow sensor (small black unit; will have a wiring harness hooked to the side of it); if the car dies, stalls, hesitates; first purchase MAS cleaner at the local auto parts dealer - specifically ask for Mass Airlflow Sensor Cleaner. It will should cost between 7-12 bucks - but you wont need the whole can - however, when using it: (if the car does not die, stall or hesitate and the idle stays the same, than the sensor is not bad) If it does however:
1. Remove the MAS (disconnect wiring harness) you may need to pull the top end of the air filter housing off.
2. Spray inside the sensor generously from both ends ensuring it's entirety is sprayed. Let stand for 15 minutes to airdry.
3. Re-install the sensor and start car. If there is still no improvement and the car hesistates, 1. Ensure the air filter as well is in good repair, and that there is nothing causing any air flow restriction between the airfilter and the throttle body.
4. If the airfilter is good, and there are no restrictions to air flow, consider replacing the MAS, however if you can get the car to the auto parts dealer, or to a technician (who may charge; auto parts dealers usually don't) have them run a diagnostics test on the car.
5. At this point, if cleaning the sensor has made no improvement, and the car stays idling, does not hesitate when tapping the sensor, the air filter is good, the fuel filter is good - then the next step is to replace the fuel pump.
Please let me know if you need further assistance.
