sparco civic97

I tried putting an ex throttle body and intake maifold on my 97 dx but it didnt work i iac plug was a rotary plug and the one the ex wasnt so i spliced it and took a rotary plug off of a wire harness i had...so now i need a manifold off of an automatic....i put all the stock parts back on andnow my car wont run i think i shorted out the ecu cuz i spliced some wires so i could extend them and i extened the wires for the iac and injectors.....if you unplug the tps and map sensor plugs the car will start up but doesnt run right it wont rev over 2 grand......im not really sure what to do or whats wrong. If i need a new computer can i just take one off and plug it right in or will i have to reflash it? If anyone could help me i would appreciate it
