Used to read the 914 parts diagram catalog like a novel and thought I had it all figured out. But after seeing an old picture in the Classifieds today of an L-jet throttle body with a spring, I realized I don't have this spring.
Porsche calls it the Return Spring 022 129 881 F. Can someone with a 1.8 L-Jet please post a picture of where this spring connects. I can see where it connects on the TB, but what about the other end? On the plenum, or body sheet metal somewhere? Thanks, Bryan |

What is the actual purpose of the long spring? It seems like it prevents the throttle from closing too quickly. The actual return spring is wrapped around the TB shaft.

It seems like it prevents the throttle from closing too quickly. probably makes it harder to push the gas pedal to prevent you from/make it a little harder to unleash all that HP (IMG:style_emoticons/default/rolleyes.gif) factory speed limiter? |
