done with mpfi swap, idles no matter what at 3k rpm, but sometimes will give me 1 or 7 code, no matter what ive tried, cant get to idle right.. what can i try, o btw way already tried swapping back the tps wires nothing.....

 

Well, code 1 is O2 sensor,

Code 7 is your TPS sensor.

Check your grounds..... Did you check the TPS sensor before installing it?

Should read 4.5v at WOT and I think .75 at closed throttle.

 

im having the same type of deal, just did the mpfi swap on my 91 crx dx and at first it was idling high like that, i started blocking off vacum lines to see how it responds. im talking about the vacum lines from or around the map sensor on the firewall and intake mani. if anyone has pictures of the lines and how they all hook up, itll help out alot.

 

On the TPS sensor you need to cut and switch the green and yellow wires on the DX harness (if you used the DX harness). Idling at 3k. Sounds like a bad vacuum leak
