Arrow URGENT! help z24i guys throttle body prob

hey infamous gurus,
I got a 87 2wd tbi z24i d21. I been having fuel problems, injector wire pinched in two under the injector cover. So i swapped on my extra tb off of a perfectly running engine. Now it has a miss at idle, sounds like its loping from a big cam. after i'm driving down the road i can't tell anything is wrong at all...(runs great, lots more power than before i swapped throttle bodies) sprayed carb cleaner around the base gasket and no change, everything is hooked up, double and triple checked. i need my truck tomorrow and i dunno wut to do. plz help guys

Check the plug wires, plugs, common stuff first.

More details on the miss, only at idle? Loss of power?

well there was no loss in power, the miss was apparent from idle all the way to about 2 grand. after that it was if there was nothing wrong with it. The only thing i knew to be wrong was the honeycomb part of the mixture heater was gone. So i took it all back apart and put in the good mixture heater and voila problem solved. Not sure if that was the issue, something i did when i swapped the mixture heaters solved my problem.
