V6 not able to have a v8 yet

probably the usual culprits then, there is a small one on the bottom of the throttle body that generally comes off or the one on the rear of the manifold plenum.

i have checked the bottom of the throttle body thats all fine but were is the manifold plenum is that just the other side to where the throttle body ose connects if so they are all fine

top center of the motor, what the throttle body bolts too on the back down a bit.
