I got a CEL for my IAT sensor so i unbolted it to see that it was broken. Does anyone know what to do since i don't really wanna take off the intake manifold if i don't have to. B18B1 engine if that's any important.

 

That sucks !!! Maybe use a pick tool and do some sideways prying... or drill a small hole at an angle to give a recess to pull on using an angled pick tool.

After you have replaced the IAT sensor... make sure that the grey two-wire plug that you are connecting to it has a red/yellow and a green/white (or green/black) wire in it... plugging in the purge/cut solenoid connector (solid red wire and a yellow/black wire) accidentally will destroy the sensor immediately.
