93 Runnin' ruff

Hey guys and gals. I've got a small problem that I'm sure somebody here can help me with. I've got a '93 bronco w/302, w/Kenne Bell supercharger and headers that were added before I bought it and everything was running fine when I bought it. Lately the engine seems to be running pretty rich whether idling or going down the highway. It runs smooth but after the engine has warmed up it doesn't want to return to a good idle when I let off the gas. Sometimes it will surge and cycle and eventually level out but sometimes it dies but will crank right back. I replace the Ox sensor and the TPS at the same time and it seemed to help for a couple days but then it went back to the same old thing. The EGR is new and the plugs and wires are new but I haven't checked the dist. cap and rotor although if one of those were the problem I would expect a rough idle or loss of power which I don't have. Let me know if y'all have any suggestions of what i should do next. Thanks in advance.

Did you check for any codes???? I think that would be your best bet.....but if I had to take a guess on what the problem is, I would say clean or replace the IAC.
