This afternoon I hooked up a system to my friend's 86 GXL, I pulled it into the air pump hose, then into a valve then into the actuators. With my air compressor I could make the ports open easy. But with the motor, nothing. If I adjust it right they with move alittle on idle down, but thats it. Not even with the valve wide open at 6k, nothing. Ideas

did you open up the exhaust? becuase the s4's required back pressure from the exhaust to open up the 5/6th ports.
|
I did the air pump mod, so you don't need the exhaust. There are no cats to supply the bad pressure anyway.
|
I dont know about the air pump actuation, but on exhaust actuation the ports only open under load, not in neutral.
|
They are suppose to open in neutral with the air pump

Did you try operating the actuators by hand? They should move easily.
