I'm no one to give advice around here.....yet..
....but I am doing my plenum pull now. I decided to just replace everything. ie: injectors, coils,actuators & all needed gaskets.... It just seems to me that while its off, do everything possible to make it run the best it can. I have 46k miles on mine........how many on yours?
I have around $760. invested so far w/o actuators.
