Today I took off the UIM on my Regal. Yes I know it'* not a H body, but seeing the engine was used from 92-94 you guys might be interested in the pictures....
I origionally started this because my thottle kinda hung up a little when I would push on the pedal from an Idle. After I took off the TB and saw how dirty it was I decided to take off the UIM to clean it as well.
Got it cleaned up decent now, I would just like to port the backhalf of the TB because it is smaller than the opening of the UIM.
