Honda Repair: racing idle, throttle position sensor, vacuum leaks

Question
I know this is not your make but the top brass suggested I try another expert because the guy in Plymouth was not responding. The problem is new to me. My first fuel injection system. Maybe you have an idea.
   My 88 ply, reliant was running so rough I could not drive it. I checked the codes and it said my automatic idle sensor had a short. I replaced the ais and found the the wire harness was shorted due to heat. Respiced the wires. Then the car idled so high I could not safely drive it. Tried letting it run so the computer could relearn the mix but it never lowered. I rechecked the codes and I still had the asi code coming up, but a new one added to it. The tps--throttle position sensor.I put in a new tps but it changed nothing. The butterfly in the throttle body is fully closed. I can not find any vacuum leaks of any significance--vacuum purge seloid should not cause a racing idle. Can you suggest anything?

Answer
Hello well i am not sure what you mean by ais. I would look into the idle air control. It could also be a bad ECM. I have had problems with chrysler ecm. I work on all kinds of cars. The  wires that were burnt did they just go to the ais . or are there more . and they can short out ecm. good luck let me know
