For 25.00 it might be good to have around?? I have run 3 different Fox TBs and 2 intakes and no idle issues per say...Clean the IAC real good before using it if its used...then do a FULL idle reset once you install your parts...Big cams are usually what porks the idle...
I have a Steeda 19 and idled mine up to 800-850 or so..works fine...
I recommend this link for the idle reset...worked the balls on mine first time out..haven't had any idles issues since...
I take that back....in the real cold weather it may surge or hunt a tad first start up in the morning..just have to hold a high idle for a moment til it gets over it then its fine...i bet a stock cam and you wouldn't have this gremlim...

I got mine at ford for about $20. I think it's a good thing to have.
