Do s4 n/a FC's have one or two dash pots? I know the bell looking thing under the intake tube is a dashpot, but what about the other bell like device behind the alternator? When I replaced my alt and was screwing it back in, the dashpot looking thing was getting twisted around.

Good? Bad? Remove it?

The FSM states its a Double Throttle Diaphram, and from what I can tell, opens the throttle plates with vacuum.

Is there a cetrain way it should be sitting?

I removed my dashpots.. Didnt notice that much of a difference.

You have 1, TIIs have two. Try to take it off and see how your car runs, if you like it, great. If not, replace it if you bent it to hell.

The rear dashpot just keeps the throttle from slamming shut.
The front diaphragm just keeps the mechanically challanged from going WOT on a cold engine.
The only problem is the 3/8" coolant circuit that works the thermo-wax module that works the diaphragm.
That coolant hose bend under the UIM is out of sight & out of mind until it blows.

if you have a very light flywheel, sometimes the car stalls on deceleration if without dashpot
