Re: Secondary Port Throttle Actuator vacuum leak
Frank I applaud your decision to stay with the stock setup.
Long term value could well be in how close you stay stock.
(or returnable to stock)
Remembering back I think it was Mark H. that found a lot
of actuators coming from the GM dealership that were defective
in the same way you're seeing.
About 10yrs ago I developed a replacement idea using electrically operated solenoids. I have them still and the brackets for mounting. All that remained was working out where to tie into the electronics which will be trivial once the need arises.
And there in lies the catch. My secondaries have not failed since I worked on them in 99. Once they do begin to act up again I intend to swap out the actuators. This will be reversible and will not require a chip mod which in itself is a potential maintenance issue. (replacement parts)
Good luck with the new parts.
