Default Throttle cable adjustment?

I noticed my throttle cable on my 91 6 speed is somewhat loose as it sits and at WOT. Is there a way to adjust it? Thanks.

It runs well, but I just got the car not to long ago. It does feel like it lacks power though.

Sorry, this looks normal to me. The "plain" cable is your throttle at it looks seated against the Throttle body.

The other cable with the plastic is for your cruise control. That will generally be loose until you engage the system and the vacuum pulls against the cable.

I'm just referring to the plain cable. I don't think it's supposed to be loose at wide open throttle.

I bet it is not. From your picture you are at idle.

Get a friend to stomp on the gas (with the engine off!) and I be you will see the cable tighten up.

The Action of the TB is counter clockwise with the cable pulling from the bottom left to right (from your photo).
