PLEASE HELP! ENGINE WONT IDLE

Just bought a 93 Mercury Sable with the 3.8. The engine ran rough when I bought it a week ago. Cleaned the mass air sensor with mass air cleaner, and cleaned TB with Seafoam TB cleaner yesterday, that helped, but soon began to hesitate or misfire.
So today I checked all the wires and plugs visually, they all appear ok and clean. Also cleaned the IAC with throttle body cleaner. Allowed it to dry, reassembled. Now the engine will not run unless I give it just a little throttle. Then when it does run, it seems to misfire horribly. no CEL. Also cant find or hear any vacuum leaks.
Please help! I need some ideas! Thanks in advance.

Did it run like this befor you cleaned the massair sensor?.. Usally just spray a little break clean on the massair element and you never touch it.
