First off turn off the CAPS LOCK. Next describe what your "complete tuneup" consisted of. How long has this miss been present? What was done before the miss appeared? What else have you done to diagnose/fix the problem?
Too many times someones posts a similar story like yours, we give some suggestions but the OP replies back, "I've already done that".

if it is an E4OD which is the most common of the transmissions for a 93 you will not have a TV cable as the shifts are controled by the pcm if it is an AOD then you would have a tv cable I dont have the AOD so i cannot tell you how to adjust the cable but it should be a straight forward process

At the very least when trying to check for codes you should get a System Clear of "111" space "111". Take a look here for the procedure to pull codes without a code reader or purchase one: Ford Fuel Injection How To Run a Self-Test. Please note, warm up the engine beofre running the code check and KOEO tests.
There have been a few service bulletins issued concerning proper spark plug wire routing. Just make sure to keep them as far apart as possible.

i did get the 111 code and the engine was warmed up i also noticed on the way to work tonite that when its cruisin at low rpms it kinda misses a little is it possible the tps could be bad? i think tps may be the stumble miss but i also think after reading on here more it maybe be the torque shudder? let me know thanks

ok another update as i was checking the routing of my wires to make sure they werent touching and i noticed i could smell antifreeze from the intake area could this be a cause of the miss and vibration at the lower rpms could it be the plunam or the intake i didnt see a leak at the thermostat but i did notice that at some point somthing was leaking under the throttle body thanks

If there is a shudder/vibration at idle as well as at speed as you indicated earlier it's time to look at some basics. Pull the plugs and look for deposits. Look for one or more plugs that look gas or oil fouled as well as dry plugs. It may be an injector is leaking or not operating properly. You could have a distributor problem (worn bushing causing spark scatter). Before tossing money at it I would also suggest a simple compression test on each cylinder.
