I just recently installed a new transmission modulator and now I'm having some issues with it. When I try to accelerate in drive it doesn't move unless I almost floor it. I had a 2 port modulator before and switched to the one port with the green stripe. I also have a tree that splits the one vacuum port on the side of the intake into three ports. When the modulator is connected to the center one with the rest capped off the cars will idle fine but when I switch the modulator to the one on the left the car will not continue running. Can anyone tell me why? Here are some pictures of it all below. (The area circled in red is where the tree is attached to the intake)
The transmission issue doesn't sound related to the modulator. Can you manually shift thru the gears when you drive? As far as the vacuum port, do they all have vacuum when the car is running? A vacuum leak could cause the car to die. Check your modulator hose for cracks/leaks and ensure it is connected to full time manifold vacuum.
