2.3TC running rich. . .

I have run into a few problems with my car lately, it has been running extremely rich and getting very poor gas milledge. . . So i figured it was an oxygen sensor, well i replaced that earlier today start it up and it seems like im down a cylinder and it knocks and shacks and it runs even worse, Not to mention it wont idle worth a shiznit, i replaced the idle controller but i dont have the proper equipment to adjust it accordingly. . . anywho I rev it up a bit play around with the idle sensor for 5 min turn it off go look at the back and theres two 3 foot strips of carbon and fuel that blew out the exhaust all over the driveway, im taking off the plugs and there black and im giving them a clean as i speak, there brand new top of the line plugs. . . anyone have any other suggestions as to what my problem may be? i know a lot of you guys have TC's on here or know plenty about them like Garrett, Shawn and Chuck so im hoping for some answers. . .

UPDATE: took plugs out they were all black, it seems when it idles it builds up carbon, than when u rev it to 3-4 grand in idle it blows it out and runs clean for a bit. . . i really should get that idle postion sensor working correctly i guess huh?

Idle position sensor? Idle air controller. eazy to setup bolt it on and your ready to go. Then pull the plug and set your base idle to about 750 RPM. double check the fuel pressure regulator hose and see if there is any fuel in it or smells like fuel real bad. That would mean that the fpr has a hole in it. Also might be the temp sensor in the lower intake between 2-3 runners.

I was under the assumption that you had to use some sort of gadget like a voltage regulator to set it up or something, you are aware that my TC is VAM and not mass air correct?

You use a multi meter to setup you throttle position sensor. make sure you set the TPS after you set the base idle. also maybe you threw a cam follower. It has happend to me. Lots of black smoke and ran like shiznit.

The idle snesor is off a 87 TC and spent 1 year in it, could that make a difference? im just throwing it out there, and about that cam follower, the car runs fine i just took it for a blast up and down the freeway, it just idles like complete , and smells like fuel. . .

Definitley check the fuel pressure.  You could also check for codes.

get a multi-meter and dial in your tps,  set it at about .97 volts this was the problem that I was having with my TC

The IAC off just about any ford car would work.

Pull the vaspoogee line off of the fuel pressure regulator, and see if there is the smell of gas in it, if not, start it with the line off, and see what happens.
It's Gumby's fault.

tried it, still runs like complete , no smell of gas was in it and i tried starting it with the line off. I also tried replacing the IAC ( Idle Air Control) and it still sputters, coughs and runs rich.

Found the problem, it was the VAM sensor, cleaned it up and bought a 6" K&N cone for it, and i noticed a big!!! differeance in low gear compared to the restrictive system it had before, Does the K&N cone actually add a little more power compared to the stock setup?
