I took my TB off the other day and cleaned it out, and the car drove fine for a few days. I went to drive it today, and the pedal has no "spring" to it, like it just sits there limp, and when I started the car, it kept redlining.

The cable on the TB is at 75% to WOT, and I can't figure out why it got so tight all of the sudden, or how to get more slack. It almost seems like it is binding at the firewall, as the cable under the dash/attached to the pedal has too much slack, but the half in the engine bay has none. I had to take the cable out of the bracket to get the TB to close fully, as adjusting it with the 2 12mm nuts didn't give enough....
