clean the idler on the intake and also clean the throttle sensor, it would also be best to change the air filter and clean the maf sensor. Idler does more than just idle vehicle it controls low revs, and drop down from reves. throttle sensor tell ecu what air to add to the fuel. and the MAF tells ecu how much air is coming into the intake. also check for broken cracked vacuum lines.

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.

Why my galant 92 model that the idle not stable in will up and down and sunddenly the engine shutt off.i change fuel pump,ignition coil,the spark plug, but still in that problem, pls help me to this...


Hello and welcome to FixYa!

It's common on Mitsubishi cars specially when the car ages. The problem will surely be on the MAF (mass air flow) sensor. The MAF controls the vacuum supply in the car and has connectivity on the air and fuel mixture.

If the MAF sensor is faulty, you'll have erratic idle. Sometimes will result to stalling too. The MAF sensor is located in the throttle body where the air intake tube is connected. Once replaced you'll be good.

Hope this helps and thank you for using FixYa!

1994 chevy lumina van. It will start and idle but stalls when gas


Try replacing the throttle position sensor. I had the same problem in my truck. It would start and run for a bit but as soon as you let off of the pedal, it would die. Try it and see if it works.
