Yea I saw that there were 2 screws holding it down. It will be quite a job to get it unscrewed as there is no space for screwdriver there :D :D

Anybody know how to fix or test an IAC? and how to tell if its good or not?
 
Most temperature sensors use resistance to send to the ecu. If you get a multimeter you can test to make sure the the resistance matches the degrees or that it changes at all

The IAC is not a temperature sensor, I think you are referring to IAT - Intake Air Temperature sensor.

To remove the IAC, you will need to unplug the IAC and TPS connectors, remove the intake duct, and disconnect the throttle linkage. Remove the whole TB, then you can get to the IAC.

Check resistance between pins 1 and 4, then again between pins 2 and 3. The resistance should be 38-52ohms. If it tests good, this would be a great time to clean the TB and IAC, before reassembling.
