the header is blocking the backpressure hole up at the block. If you take it off you'll see it. Also, look at your stock manifold or gasket. There'll be a mysterious hole in it, that's how the actuators get their backpressure. That hose going to the cat is a different thing. It won't do a thing for your actuators.

the 84-88's have a seperate hose for the actuators

The ports will only open under load, revving the engine does not produce load, You have to be driving it. Put a hunk of grease on the bottom of the actuator rod, go for a spin then check after to see if it is smeared..

I'll give that a shot.

Mike, how do you re route the air pump to activate them and will it do it at the right rpm or just open them all the time? I have mine wired open right now and it does suck for driving around town at low rpm... temporary until I get my new cat installed. [/quote]

you tap a fitting into the airpump hose, and you put a bleeder valve on it so that the ports open when you want em too

hmmm, good idea.. I guess you could still remove your ACV then, run a header with no backpressure tube, whatever....

uh i know i have said it before but i just ripped out the sleeves all together.

i honestly have not noticed a drop in performance at low rpm's. the car is still very driveable and it was a slight gain on the top end. ask vosko about it.

he has driven the car and can concur with the what i just said.

did that...I didn't see any evidence that they had moved

could the kinked rubber hose before the check valve have any affect on it?

I really want these to work

later today or tomorrow I'll try the paper clips instead of the grease, in case I was misinterpreting what I saw
