Very Rough Idle just started today! HELP!
I have the 5.8 EFI and it has been running fine 162K on the engine. Tonight when I started the engine it ran very rough, almost sounded like a funny car at low idle. I just put new plugs, wires and, cap and rotor in a few months ago. A friend at work said it sounds like the choke is stuck shut as he could smell how rich the exhaust smelled. I didn't think the EFI had a choke. I drove it home but I had to shift from drive into neutral to keep the rpms high enough so it wouldn't die on me. Anyone with any help I would sure appreciate it.

Is your CEL (Check Engine Light) on? The first thing to do is to check the codes. They are stored in the computer even though the CEL is not always triggered by them.
There are a number of ways to check them. A code scanner can be purchased for about 30 bucks, or some auto parts stores can check them for you, usually for free since they hope to get your business buying the needed parts. Also, you can check them yourself with an analog multi-meter, and there are other methods that use a jumper wire. Here's a page that explains how to do it:

Here's a page on the IAC that hkiefus mentioned, and how to test it:

There are several things it could be, pulling the codes is always the best place to start.
