Throttle Body overhaul...calling Bruce Arnn
I am trying to wrap up an overhaul of my throttle body with the Arnnworx kit and I ran into a few snags/concerns.
1. Per the Bruce's documentation, the image that show the relationship of the hardware on the cable end of the shaft there appears to be a washer in there. Is this right?
2. Where can I get my hands on that funky circlip that goes on the end with the TPS? I may need to take the new one of and try again, but they don't seem to be reusable. Would a normal circlip from Home Depot suffice?
3. The disk that blocks the airflow is a bitch to reseat....
4. The return spring must have gotten stretched out and will not make the throttle close. I am talking about the long one, not the one on the shaft. If I let is whip back from WOT, it will close competely, but any partial throttle will leave it open by a few degrees. Where could I get a new spring?
4b. I bet that is why my throttle was acting wierd.

To answer some of my own questions.
1. Yes there is. I didn't see it in the solvent I was using to clean up the parts.
2. I was acutally able to use the clip again. Good to go there
3. It fit with no problem when I put in the washer from #1
4. Still won't close fully. Now I am on the hunt for a new spring.

Well after looking at LR, Paragon, Pelicanparts, 944online, Autoatlanta, PET and eBay, it appears I am going aftermarket.
I going to try some local parts shops to see if I can find something like this from Jegs. I will let you all know how it works out. I would imagine with a new return spring it would pop the throttle closed and end the fluttering idle and high rpms at idle.

Did you ever find anything?
Had to throw a generic autozone spring on my car at the track the other weekend. It works ok, but its not as stiff as the factory spring.

I ended up finding a kit at Advanced Auto Parts that works well. It was a pack of 6 different springs for $12. One of them works a lot better, but still does not "snap" back as much as I would like, but it does now close.

I just rebuilt the TB on my brother's TB - I had the same problem with the spring not pulling hard enough to hit the microswitch. I am going to put a slightly hotter spring on it and call it done - everthing else worked out great - got the kit from Paragon, probably the same kit that Bruce sells.
