FORD F-150 THROTTLE BODY PROBLEM

1993 Ford F-150 • 180,000 miles

302cid, auto trans 4x4-truck running 2500 idle, wouldnt kick down so I turded off. Now wont start. Have spark to plgs, fuel to injectors any help apprieciated-do not have tester for code and really cant afford one. Will most likely go to junk yard for parts, the usual, low income

Clean out the idle air control, throttle body/plate and also look for vacuum leak-start here and let me know-also refer to this walk thru link: http://www.2carpros.com/articles/engine-idles-too-high

Use carb cleaner, small bore brushes and if available a vacuum gauge

5.0 Liter the IACV is located on the throttle body assembly see pic below

Thanks rasmataz ILL give it a try in the morning.
One thing I forgot to add, when it was running sometimes it idled fine, then about a month ago the idle started jumping up and down and wouldnt kick-down manually. Once shut off and started up again it was usually o.K. For awhile then out of no-where it'd start jumping up& down again.
Thanks again
