Like many of the "FBI" gang, I removed my SPTs - the entire harness, butterflies, throttle rods, pump, vacuum lines - everything. Maybe someone has the # handy for the Dorman freeze plugs that are inserted in place of the throttle rod bearings. (And, for good measure, I put JB Weld around the edges of the plugs before I installed them for a permanent seal.)

I NEVER missed them for a single moment. The input valves both get washed constantly and so they don't have any coking buildup going on. And, talk about instant throttle response!

IMO, there is NOTHING not to like about pulling the dang things. However, it is a moot point now, as my "FBI" porting exceeds the stock diameter significantly.

Parts that don't exist never break. And, they don't cost much!
