Fails to start, I noticed

Appoligies about that, I use a screen reader and had some dificulty getting it to submit, and the first title box only allows 160 questions, the question was, Have notice the throttle fethres itself slightly a few times when releasing the key, in the event it cranks, but doesn't fire. Does this solinoid/part have a specific name? Or is it part of the actual fuel system. Some one said this was the fuel system trying to prime itself again. Have only herd it on a vehicle of this make/time period.

Thanks, sorry about the dificulty earlier. I am not to sure either, being as I am blind, so am going soly by sound alone, and it currently sits over at my parents house, and hasn't run in about 7 years, so been a long time since I have herd it, but its rather interesting, never have had a vehicle do that and fethre the gas peddle 2 or 3 times, but I imagine it would be the airflow sensor. The only other time I have seen one do that, not related, but in a simmiler fassion, on some older GMC school buses, there's a solinoid and a feature that when the key is turned to on, not started, that it advances the throttle slightly, but thats called curb idle. Never knew exactly what that was suppose to be for. Will deffenetly give that a look when I get it running again in the next few years. Thanks for all the help, I appriciate it greatly!
