About a month ago istart heving problems all of a sudden my cars r.P.M.S. Would surge back and forth I went to the local shade tree and they told me that it was my throttle position sensor, well I change it and it seemed to have fix the problem until yesterday it started doing the same thing, so I thought the part went bad, I took it back to auto zone got another one installed it and the problem is still there.I disconnecteed the the idle control sensor and it runs without the surging, but it seems strained. What to do? 8) ? :Idea:

Try cleaning the throttle body. After the throttle body is cleaned, disconnect the battery, touch the two cables together, hook the battery back up, turn the ignition to the on position (don't start), wait 10 seconds and then turn the ignition off, wait 10 seconds, then start the truck.
