Idle Help

I have a 94 F-150 4X4 with a 302. I have changed the plugs,wires, IAC Valve, EGR Valve, Mass Air Flow sensor, and I still have a terrible idle. It barely runs at all. I have ran fuel injector cleaner, I'm kinda out of ideas here. I have not done any other tests, is there anything that anyone can suggest I do here? PLEASE LOL I need to plow SNOW! Thanks guys

Have you checked for vacuum leaks, Timing, Checked the EGR system, PCV valve, Air and Fuel Filters, checked fuel pressure and vaccum level ?

No, I have not ran any of those tests. I just got the truck a few months ago and I am not very familiar with the 302 engine.

Might I suggest you pull your codes first then.
You can pull them yourself, visit http://fordfuelinjection.com/?p=13 to learn how. All you need is some jumper wire or a paperclip. OR you can spend $30 and get a ford code reader from your autoparts store or walmart. Grab a $15 haynes or Chiltons manual while your there unless you plan on gettng a factory service manual.
Post your codes and we'll be glad to help figure them out.
