I'm in the process of trying to remove the UIM, I've removed all the nuts, unhooked everything as to the manual (hoses, coolant hose, etc.) but there is something holding it on the Throttle Body side from underneath. I can't see what the heck it is, but it won't let me pull the damn thing off. I can get it about an inch up on that side and that's it. What could it be and how do I get to something I can't see? Help, please.

 

Same thing happens to me the 2nd time I tried to take it off. I don't remember I got it off the first time.

 

how about the wire underneath and in the middle of the UIM? did you disconnect it? i remember there were 5 screws from the UIM to the LIM. One screw near the throttle body.

 

the air temp sensor... look from the front of the UIM, underneath it, and use a flash light its in the ribbed area of the uim about 2-3" under it... or just use your fingers...

 

There is a coolant line that is really tough to get off the bottom of the throttle body. I am sure thats what you are still hung up on. You have to kinda turn the UIM on its side a little to reach the clamp that holds that coolant line on, good luck.

 

thanks guys.
