4.0L HO Jeep Engine Build
With the addition of the BBK 62mm throttle body, the old IAC and TPS need to be installed. They do include a T20 Torx Security bit (has a hole in the center) but I also have a set just in case anyway. My old IAC body was pretty carboned up so I got that cleaned up and installed with the new BBK supplied gasket. Very straight forward swap. The TPS needs to installed by clocking it forward so it meshes with the blade on the throttle shaft and rotated back till the holes align and of course, the TB should be checked for free movement afterward.
While mocking up the BBK TB I also found that the throttle lever would hit the manifold at WOT which could cause a very dangerous situation. A quick look revealed that the "Angle of the Dangle" was not 90 degrees so a quick adjustment with my handy dandy angle adjustment tool (pliers) solved the problem. :)
