weird starting problems

(also have this in the superduty section)
for the last couple of days i have notice that my truck isnt starting properly. it will turn over, sound like its going to start, then when the rpms come down from what the start has spun them up too, its like someone turned the ignition off. i thought maybe the truck had a clogged fuel filter so, replaced it yesterday and this morning it did it again. if the truck has been running already then it will start just fine, if it has sat overnight it does the strange start up i described above. i used my hypertech powerprogrammer and i got a code 7A00 that might be linked to the problem maybe not. any ideas would be greatly appriciated.

Sounds like the IAC is clogged. If you give it a little throttle does it still shut down?

IAC - Idle Air Control motor. Buy a new one, unplug/unbolt the old one, bolt on new.

how much for the part.
between $55 and $70 depending on maker
is it a whole unit or a valve type thing.
Remove/replace whole assembly.

Sometimes they can be cleaned and re-installed. With your miles a new part would be in order, in my opinion.

im going to just clean it with a little carb cleaner. i havent been using my truck very often since fuel prices are so high, but when i do it usually a very short trip. not good at all for the truck. im thinking it probably got a lot of carbon in it. my friend has said he had the same problem with his cars 87 t-bird super coupe 89 super coupe 96 cougar. he said he just cleaned is with carb clean and is was good to go. thanks for the help

Your choice, adam, but if you're going to remove it anyway and with those miles....

Just be sure you get it sealed good and proper.

Let us know how it turns out.
