Hard hard HARD Idle

My truck started idling really hard the other day. When I say really hard I mean it was rocking from side to side. It was making a weird noise like someone was tapping the gas and revving it up on a rythmic pattern. I changed the IAC and the throttle body was already new. It eased off some but its still not quite right. (I haven't had this truck two months, I bought it used...i think I may have gotten duped) I'm not sure what else it could be. I also just realized that the horn doesn't work (relay clicks but the horn doesn't blow), wipers only work on high and the odometer and gas gauge only work sometimes...also the A/C wont blow cold. I don't know if that has anything to do with the engine idling so hard to where it shuts off or not but, there we have it. Any suggestions?

Not sure if this is too late...but if this happened all of a sudden, sounds like an electrical short in the fuse box somewhere. The A/C, Ignition, and wiper relays are all pretty close together, no? When power shoots over to other circuits when its not supposed to, all sorts of craziness can result. pull the fuses and relays for the affected parts and visually inspect and perform continuity checks. Pull up the fusebox and check the underside of all the wires. Unplug harness connectors and look for any gaps that are bridged with rust, corrosion, or overly exposed wires. After running the truck, is there a burning smell near the fusebox? Very indicative of a short. Get you a wiring diagram and a multimeter and have fun playing detective!
