Jumping between 1500rpm to 2500rpm

I just finished my zc sohc swap, it idles fine but when I step on the gas, it starts jumping between 1500rpm to 2500rpm. After that, the car drives fine. Can you guys please help me find the problem? and now the radiator fan is not working. It was working before the swap. What should I look for?

Could be your IACV. cech your ECU for codes. DId you hook up the coolant fan switch>

distributor... check the ECU codes. most likely the crank angle sensor.

if the car stutters I would chech the throttle position sencor. as far as the fan goes check the relay and wire it hot if you have to it will just run as soon as you give the ignition power just jump it with a paper clip ..
