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.
stalling son in law is a mechanic and diagnosed the problem, I got the part and husband put it in.
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
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
MAF sensor failed at 140K miles. Was constantly stalling for about 10 miles then just refused to start up again.
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
Car stalled out at all speeds, all RPM. Finally didn't start at all. Mass Air Flow Sensor was bad.
Driving down the road the car sputters a bit and stalls. I put it in neutral and turn key off and restart. Off I go.
Still on going. Check engine light on. Changed mass sensor... Evap my ref is up this month any suggestions?
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
