Identifying throttlebody type (gen 3 motors)

[SappySE107]

To make it easier to figure out what throttlebody linkage is needed between applications, I am going to post up pictures of the different types as I come across them. These for the 3100/3400 engines. If you see something that looks like yours and I dont have the year/motor listed, please let me know. If you have a throttlebody I dont have listed here and can take a pic for me, please do so. I will eventually get this info on the main site but I want it as complete as possible first.

This is what the 97-98 3100 throttlebody linkage looks like.




This is a 3400 Grand Am from 2001-2003 Throttle body

nm. u just edited it.

Does your 95 look like the 97 throttlebody?

I can verify that the linkage in the first 2 pics were used in 95 (minus the coolant lines) and likely as early as 94.

my '95's linkage is all- steel but functionally looks like the 1st one you posted.

The TB from an '01 Impala looks like your last pic posted.

Thanks I know the A body cars got a different throttlebody so im not sure if these billet ones will be compatible. Seems like that is the only platform difference so far. Are there only 2 types of throttlebody linkages then? 94-98 and then 99-05? That would be nice, even if its all metal for one and part plastic for another but they function the same.

I have a '95 Lumina 3100 and swapped to a TB from a '00 3400 here with the plastic on it. I discovered there is a difference in the area where the cable wraps around. The 3400 TB is slightly larger and raises the pedal. On mine it raised about 3/4 inch causing the TB to max out before the pedal hits the floor.

03 3400 from a Rendezvous:



I have this TB on my bench in my basement so I can grab better pics tonight.

My 3400 is from an 03 buick Rendezous

[SappySE107]

That looks like the older type. Ok, so maybe its not year based at all. That makes it a little more difficult then.

Heres some better pics of my 03 3400 Rendezvous TB

[SappySE107]

Ah ok, its a metal version of the plastic one I think If that is compatible I will hunt those suckers down too. I dont forsee many rendevous owners looking for a larger TB but maybe im wrong.

[germ]

just an fyi, i think there is at least one more version of the TB linkage.

i have 3 different ones at home, and only 2 of them match the pics posted.

i will see what i can do for a picture so you can see.

im sure it came off of a 52mm tb, but no idea the application.
