Why am I leaking gas from the shaft that controls the Throttle Position Sensor? Its a little leak thats coming from around the spring on the shaft. Its running down the side of my manifold. What kinda seal is it "O" ring or somthing?

 

I am only guessing here, but what I am thinking is that the throttle shaft that goes across the TBI to the accelerator linkage may have worn a hole in the TBI where the shaft pivots at the TPS unit. I'm not sure if this helps or not. Good Luck.
