Need Help How To Reattach The End of The Secondary Throttle Cable of My 1990 964

[David Schmidt]

I have a 1990 964 C-2 Coupe that recently developed a few oil leaks. One was due to a faulty Oil Pressure Sending Unit. In fixing that problem, I created another one that required my immediate attention. The new problem was an inoperable SECONDARY THROTTLE CABLE (the one you see when you open the engine hood) that I created when I moved the cable to remove some fuel injection parts. Apparently moving the front half of this throttle cable can cause the end of the cable to become detached from its mounting. Now, the cable will not function at all! This cable is NOT the main throttle cable that runs through the center of the car to the gas pedal!

I’ve included a photo of the cable to help answer the questions I am about to ask. The PHOTO shows the cable in a large context showing it crossing over the top of the right aluminum intake distributor to get the proper angle of attachment on the throttle housing.

QUESTIONS:

1) What does the far end attachment point of this throttle cable look like?

2) How does the cable attachment mechanism work?

3) Can the cable end be reattached without directly seeing it?

4) If not…what parts need to be removed to get enough access to reattach the pesky cable, tension spring or whatever the problem is that is making the cable slack?

ATTACHMENT LOCATION OBSERVATIONS: The cable attachment point is located behind the air cooling turbine, beneath the fuel injection connector tubes…and near the point where the main throttle cable (that runs from the gas pedal in the cabin) links up with the fuel injection system. When I followed the cable back with my hand, it feels like there is a pivoting arm where the cable is attached…but there is no tension on the cable, as if a tension spring or something else, came off when I previously detached the cable at the throttle housing. I am just guessing.

I would appreciate it if someone who has seen the area in question would help me out. I'm at my wits end.

I apologize a thousand times for the misidentification of this cable. It is linked at the throttle body to the main throttle cable and...well, being a novice, I assumed they worked together in the operation of the fuel injection system. I learned something new about my car and my own fledging diagnosing skills. I must say, the Porsche Parts Manual is VERY weak in illustrating this portion of the car.

Well, I still have an issue with my cruise control cable, but I will do some more research on my own to try to figure it out.

I would still like to know if you have to take out a lot of fuel injection tubes and other parts to get back there to reach the base of the cruise control cable, or if there's an easier way back there only the guru's know about.

Thanks,
