I found the little black box, now what..89 740 b230 700 1989

I found the box by the strut tower I think I can find the codes, but how do I know what they will mean?? Will they tell me if the tps is bad or out of adjustment? Will they tell me if the iac is no good?? In my last posts, the car had all kinds of problems, but after replacing nearly everything, the car still has this weird idle problem. Now after it warms up, the idle is really low almost stalling every time i stop. If it doesnt stall, when I try to accelorate from a stop sign or light, when i hit the gas it is pretty unresponsive until i put the pedal almost all the way to the floor, then it bucks and reluctantly takes off. The past few posts tell all the parts I have replaced and what i have cleaned, but does this sound like faulty tps, of iac. WHAT IS CAUSING THIS TERRIBLE IDLE PROBLEM??? Any suggestions??Thanks in advance

Well in the past three weeks I have replaced: the spark plugs, dist cap, rotor,
wires, FPR, both temp switches, cleaned throttle body, adjusted TPS to specs, all vacuum hoses, oxygen sensor, and finally the AMM. I also replaced the
exhaust system, although unrelated. My problem is that I cant get the car to idle at a certain speed. It seems to either idle high (1200rpms), low (500rpms), or eraticly between 1000 & 1500rpms, depending on its mood. When driving the car, other than the idle problem, there are no other problems except a VERY MILD hesitation upon take off. I am going to clean the fuel injectors and replace the seals next weekend. I also replaced the fuel filter, cleaned all grounds, but I am running out of ideas. The cost of doing all of this is starting to build up, but I just want the problem solved. I noticed a small bit of moisture in the TPS, but I dont think that is the problem, or is it?? Im calling upon anyone who can help me solve this ongoing nightmare...

thanks in advance
