starts and stalls

hey guys! i'm dropping in from the expy forum (my truck), but my bro is having issues with his '99 explorer sport xlt 4L v6. it'll start, but then quickly dies (seconds after it starts). i was able to give her some steady gas after starting her, and then i slowly let up on the gas and she seemed fine - drove her around a few minutes too.

we're going to get a fuel filter (+haynes manual) and some fuel injection cleaner - any other suggestions?

thanks
al

Sounds like the idle air controller (IAC). I've replaced three of them in the last two weeks.

Hope this helps

thanks for the replies guys - i'll look into those.

think i'll try the IAC first since it does seem like a start-up-idle problem. the idle jumps up but then falls too quickly and goes too low (at least that's how it seems to me - my expy idles at a higher rpm when i first turn her on, and takes longer to settle down)

was the IAC hard to replace (haven't got the haynes yet)?

You can try cleaning the IAC before actually replacing it. Fuel filter would be the 2nd thing to try. Fuel pump would be the very last thing to try.
