Throttle cable adjustment and sunroof panel rattle

[SPR]

When I was cleaing the throttle body, I noticed that it wasn't opening all the way. Also if I push on the cable there is some slack in it. I went under and looked at the accelerator and noticed there is a threaded farrel which appears to be there for this adjustment howevever I couldn't see how to turn it without possibly breaking the plastic where it goes into the body of the pedal. There are two nuts on either side of the threaded farrel do these need to be turned? I also noticed a screw which holds the plate to the floor and a covered panel which I could not pry out just below it behind the accelerator pedal, what is the panel for or hiding?

I also had my girlfriend floor the pedal and there was a bit of play between the stop and the arm of the level which I would assume it hits when fully open.

Any thoughts?

OH also I forgot to ask, I have the dreaded rattle from the sunroof. However, when I push on the cover for the sunroof it stops. I can actually push the cover up and down is this normal or did it come unglued or undone? The rattle is really annoying should I glue it or insert foam or something? thanks Sean

I have the dreaded rattle from the sunroof.

The reason for this could be that you are missing the edge guard. When this is missing the roof can hit the sliding roof frame and make some noise.

Check out TSB 6028 on this site. It will give you some info. Looks like the fix is pretty quick if the edge guard is missing.

Cool I will check into it. Basically from my diagnosis the sunroof panel is tight everywhere but right at the front center and that is where the rattle is coming from. I installed a suede headliner some time ago, and maybe I unglued it or something? I will check that tsb to get a better idea of what you're talking about

Anyone have instructions on how to adjust the throttle? thanks!

I looked and it doesn't seem to directly address where my rattle is - the front middle of the sunroof trim panel when closed only.

How can I adjust my throttle cable without breaking the accel. pedal? thanks.

No one? well I guess I will experiment hapzardly and pray not to break anything. The weird part is that the top nut above the farrel is already loose and I doubt it should be. I would guess that if I loosen the farrel to the bottom nut I can adjust then lock it down with both nuts.

Here is what you can do. There is no real way to adjust the throttle cable however having owned 4 Porsches I have found a realatively simple way to fix this and squeeze that extra little bit of movement out of the throttle body. Hold the throttle butterfly open with a tool (wrench, screwdriver etc.) slip the cable off of the catch. Now take the cable that has the small cylinder at the end of it and fasten a small zip tie onto it. Just click the zip tie all the way shut and snip off the extra (tail) replace the cable onto the holder and it will hold secure however now that zip tie takes up that little extra bit of slack. Just the amount you need. I did this on a 99' Boxster (same set up) and it worked fine until I sold the car and that was several years. Kind of half A__ way of doing it but it works. Regards...

nice that's actually a decent way to do it, however that farrel has to be for that express purpose. I am going to try and adjust it with the farrel, and if it doesn't work I will try the zip tie solution. Thanks. Sean
