Robby got the shaft bending from my 2.3-16 project
and I doubt that it applies to your engine since you are not experiencing throttle bind. The stock Mercedes throttle body would bind when under boost. I solved my problem by switching to a Mustang 5.0 throttle body. I also converted to an aftermarket SDS Injection system
. Good luck, that is about all of the advice I can provide.
