Yea you are definatly right about that. thanks for the help. I have read some of ur responses on some threads and was wondering if you might have any advice on the infamous lean front and rear bank code. Are the upper and lower intakes on the gen 2 3.0 3.2 bad about leaking hence the lean code? The code I am throwing is saying my o2 on the upstream and downstream are bad but would a leaky upper or lower intake cause this code? Also one more mind boggler for ya if ya dont mind. On the bottom side of the upper intake right behind the throttle body there are two vacume ports that are capped off is that factory? I am also wondering about the routing on the firewall vacume log if u have any knowlege on that? I cant seem to find any other posts that pertain to my motor/year? Thanks again for the help.
Well I would maybe consider swapping the O2 sensors.
The intake rarely leaks unless any work has been done and if then it would be the intake couplers as due to their age they can crack. You can check for vac leaks to confirm. If you need to replace them we have them here: V6 Intake Coupler Hoses
There are no vacuum ports that should be capped off unless you are talking about the ones with the hex screws in them. If so those are just casting paths for the EGR.
Where do the S/C lines run when they come off the "T"? I have one vacuum line that comes off the T and is black with a white stripe and the other side is a solid black vacume line. Where do they run in your pic?
Yea my diagram has some general routing but not from the vac log on the firewall plus mine has a 3.2 swap and he changed the shroud cover so I question if that is even right?I just cant for the life of me figure out where the two vacuum ports on the bottom side of the manifold right behind the butterfly are for and where they go to? The ports were capped by previous owner...
