today I started my car.. the car was cold first start all day.. it started and idled for about 3 seconds than it shut off....i go to start it up again and it started up fine and i drove it fine..any ideas to why it died?

 

How cold was it outside?

 

i havent drove it since last night....last night was about 40 and today it was like 55 when i went to start it

 

what year is it, is it carbed

 

Simplest thing to start is get some carb cleaner. What year, motor, EFI? Hold the throttle open a bit and spray it while running about 3 good shots, then turn it off, spray it again with one good shot, wait a few minutes and start it back up. See if that helps. If not, you mayn need to take off the IAC and clean it out that way. Try that first and let us know. There are a number of possibilities if that doesn't help. What does the car idle at when at normal operating temp? May need a slight boost up.

 

1993 mustang lx 5.0 5 spd....not carbed

 

this is the first time it happened...I started it and it idled for about 3 seconds than it shut off.. i started it again right after and it was fine...my car idles at like 700 and i never had a problem before

 

Do the same, get cleaner for EFI, basically the same, take off the CAI tube that connect to the throttle body and spray it thru there.

 

is it bad to clean them when they have the sticker that says do not spray any cleaner becauseof a special coating....or something i cant remember exactly what the sticker says i just remember i was spray some tb and intake cleaner and i saw that so i didnt do it.....the tb looks pretty dirt is why i am asking?

 

Not sure about that, maybe it was the MAF sensor or not to spray the outside of the TB, but never heard of that.
