Started stalling intermittently for several days. Tonight it stalled while going 45mph. Put it in neurtsl ans started engine. No warnings on instrument panel. Stalled at light but refired and acted like it wasnt getting fuel. Changed out MAS 3 months ago. Gonna look at position crankshaft sensor. Ill let u know what i figure out.
Car dies while I drive and I have to keep it revved up to drive also if I slow down or stop at red light\stop sign it dies
stalling son in law is a mechanic and diagnosed the problem, I got the part and husband put it in.
it was stalling out. restarted fine. check engine light came on and stated it was mass air flow. replaced it. now it doesnt want to stay started idles below running.
I can drive vehicle long or short distance turn it off it wont start back up after sitting for about a hour than start right back up
my car will turn off after about 10 minutes of driving, it will start back up after i let it sit for about 4-6 minutes
heisting when taking off...
MAF sensor failed at 140K miles. Was constantly stalling for about 10 miles then just refused to start up again.
Crankshaft sensor was the problem .
Expensive, but easy fix by mechanic. Less than $500
I recently noticed that the air flow sensor or really I think it is is missing from the fuse box I just wanted to know if its mandatory for it to be there so that I can replace it and where we need to go to get it if I can just go to any store I have to go to Charlotte thank you please let me know
maf failure.
Stalls. early on it would start right back up. Now it takes hours or even overnight
Car stalled out at all speeds, all RPM. Finally didn't start at all. Mass Air Flow Sensor was bad.
starst and then cuts off cut off at 55mile an hour
Car starts then dies bout 10 mins later then won't start
I drive the car for about an hour on hot days and when I get on to traffic it shuts of I still have the problem
engine stops running won't restart until cools down
Car stalls after about 10 or 15 minutes of driving after letting sit for a while then maybe it will start sometimes it stalls again shortly and sometimes it won't
Intermitant stalling, would restart after a few minutes.Seemed to be getting progressivly worse with warm weather. Following suggestions in this resource, and position sensor code PO336, changed out sensor. Been driving a week now and no further problems. Thanks to all for their contributions.John R.
