Today as I was pulling out of Lordco whenI friend of mine, who I hadn't seen in a while, asked me to show him what my car could do. Naturally I agreed. The problem came when I shifted into 2nd gear and slammed down on the gas pedal. The throttle cable's plastic clip broke and instantly I had a tone of slack and about half throttle, even though I had it matted. If you are looking at the TB it's the clip that holds the throttle cable to the TB on the left side. I made a quick fix but I still don't get WOT. (this could be a good thing

)
What do I need to fix this?
How much?
Can someone get me what ever it is I need cheaply?
