Engine stalling

[brownb2]

I've been having this problem for about a year now I'll be driving and all of a sutten the motor dies I dont have a problem restarting the car but it will do it at all different speeds.

Any mods done to the car? How many miles? Any check engine lights on etc?....

It is a 02 gt Cai accel coils thats bout it had the car for about 2 1/2 years 110k on the dial

Have you tried scanning it for codes? You can take it to autozone and they will scan it for free. Off the top of my head... I would suggest its possibly an 02 sensor if they've never been changed.

I've got a handheld scanner and it has not thrown any codes and I just have to do emision test bout 3wks ago and it passed with no problems I never charge the o2 sensors

battery/grounding issue?

^ +1 good suggestion as well.

Does the car hesitate when you give it gas or does it have a miss or anything?

Its also possible that your car is not throwing a code. It wouldn't be the first time. Replacing the 02 sensors still might not be a bad idea since the car is over 100k.

 

[brownb2]

Not all the time but I do get a miss at differnet rpm ranges. I also forgot to say I change the fuel filter wiith in the last 8months.

 

[cl0udedth0ught]

Have you changed the spark plugs yet? If you don't know if they've been changed by a previous owner, I would change them out with a new set of motorcraft plugs.

 

[brownb2]

yup changed the plugs to motorcraft and coils and fuel filter the same day.

battery/grounding issue?

+1 on this as well. This is a PRIME symtom of a bad battery.

Just in case you thinking this couldn't possibily be a bad battery because the motor was running at the time, you are wrong. Today's car require the battery to excite the alternator's field coil.

no battery = no alternator.
