Dumb Error on throttle linkage

Well in modding out my engine the linkage rod from my throttle to the rod that goes to the assembly next to my tranny became undone. In fooling with it I think i screwed the whole assembly up (did not connect it correctly) because now when I push the gas pedal down it stays down and does not spring back. Also from the motor side, when I manually move the throttle and spring, the gas pedal does not move.

Everything was working before the rod that goes from the throttle thru the firewall and then links up near the tranny became disconnected. Does anyone have a pictures of how the throttle body linkage is all connected, along with how the throttle body with spring is supposed to look and correctly connected.

There is something I did wrong in hooking the rod and everything up because like I said everything was working fine before. I just need to see pictures of how everythjing is supposed to look like connected correctly.

And yes, I posted this after doing a search on the forums for an hour and I did get some info

Any help would be greatly appreciated.

But that is what is confusing me. In the above picture the linkage is connected to the V pointing up wards. That is the space forming the V is facing up. But in other threads I researched people said the V opening should be facing downwards or to the sidelike in this picture

Thanks so much for going thru all of that trouble. So that gives me an idea of how the throttle body (engine part is supposed to look.

What is really throwing me is how does the connection of the rod down by the trnny supposed to look. Is my V arm supposed to be pointing up or down. Here is a picture I found of the connection near the tranny. IS this the correct positioning of the Vshaped lever

http://forums.pelicanparts.com/uploads13/ACC1215403217.jpg

One last question: How many springs are there supposed to be on the throttle body assembly. I only had one when I put things back together, Am i supposed to have two springs

This must be your lucky day ... lol ... my car is on stands in the garage so i took a few more pics for you !The curved part of the lower linkage goes over the axle and into the engine bay.
The extra spring you see at the gearbox linkage is my home made "no more hanging throttle" fix ... works very well

Here you go !

You are a life saver. Those pictures are exactly what I needed.

My last question goes to the engine bay where the actual throttle body is. On that assembly how many springs do you have on the throttle body itself. DO you have one or two springs (don't count the one by your tranny)

There is only one spring on the throttle body,although at one point i had added a second one when i was chasing down my hanging throttle issue !

JJ,so you like my fix
I think i picked up the spring at Rona in the hardware section !
Actually CDN Tire has a good selection in the lawnmower/tractor section as well ...
It doesn't need a lot of tension,just enough to snap the throttle pedal back !

Cheers !
Phil

On a 3.2 there is a second throttle return spring on the underside of the intake. Spring runs from bracket at back(front) of the engine to a hole cast in the bottom of the left side intake. Sorry, I don't have photos handy. -J

ETA link with lots of photos. 3.2 throttle return spring differences

Jar0002:

Okay I went to the cite that you posted and I could clearly see the two springs. But where do they hook to. I see where you wrote "Spring runs from bracket at back(front) of the engine to a hole cast in the bottom of the left side intake."

From the pictures you referenced it appears that there are two bottom springs + the top spring making a total of three springs. So, now I am really confused and lost.

I have 3.2 liter engince, 87 Carerra. Could you really help me out on this spring thing because I am not getting any action on my pedal

On my 86 I have two springs total. One on the throttle body and one underneath the intake. I had no idea some cars had two under the intake until I searched and found that thread. My spring under the intake is similar as the left/outboard one pictured in the linked thread. I'm on an I-pad so I'm not even gonna try and paste in photos.

The spring connects to the linkage on the back of the engine. It's hooked to the rod that runs from the side of the trans up through the engine tin. My visualization is that it pulls on the rod when you release the accelerator pedal. It's tough to see with the engine all together and installed. If yours was set up this way and the spring broke you'd never see that unless you knew to look.

I recently replaced intake gaskets and it was fun getting that spring re-installed. With the auxiliary blower and tubing removed you have better access. I still had to resort to a seal puller(hook) and pliers to re-install.

Does the throttle rod move with the pedal at the point that it exits the tunnel through the bulkhead? There is a connector just inside the rubber boot from memory

Yes it does move. When I push the rod it moves the pedal and vice versa
