I can't seem to find any decent help anywhere on the internet except here. So my question has to deal with my 95 F150 with a 351w. I have a high idle sometimes and it stays there. I pull the plug from the IAC and it idles good. Is this the problem. By the way it is speed density!!!
Thanks

Bryce, I know it's been a while... but, any updates? Did you get it fixed? I ask this because I'm having very similar problems with my speed density 5.0 in my Mustang . Borrowed an IAC from a '91 Grand Marquis 5.0, same results. Maybe a vacuum leak?
