Default Throttle Body Removal

Just started teardown for UIM/LIM gasket replacement. Lower throttle body mount bolt
a bear to get to along with bottom rear stud turning. Read earlier posts of removing crossover duct. What works in these tight areas? Universal 8MM:? What about stud
turning. Upper is about ready to come off. Called it a day.

The rear bottom nut I could reach from the intake end of TB by using a 4 inch extension from a small socket set I had bought. I believe those were 8 mm.

I had a short box wrench to use on it also. There was just enough room. I didn't have any touble with the studs for those three turning.

Pull the UIM with the TB on it.

Then remove the TB by holding the stud. You're replacing the UIM anyway.
