Need help diagnosing my 5.0
I have a '91 GT with the Ford Racing Crate motor in it. The car just does NOT like to idle on its own. Say .. if I to back into a parking spot the car just shuts right off. Also, while I'm cruising around/under acceleration the car bogs down for about a second and drives like normal right after, then it bogs down again..and so on. It 'bogs down' very often while I'm driving. (sorry I can't think of any other way to describe it :/ ) Does anyone know what this could be?

RE: New help diagnosing my 5.0
Honestly this could be too many things. You need to start eliminating potiential problems. You should have some sort of manual, preferably a Chiltons, and a multimeter. Start with the easy stuff.
Ignition system - timing, plugs, wires, rotor, cap, etc
Intake - filter, tps, tb etc
Exhaust - o2 sensors, smog assembly .............
Scanners / code readers are helpful sometimes also. You can find them on ebay for $20 to $30 bucks.

you need to put a code scanner on it, but it sounds like your IAC is bad
