Sweat deal man, Post up some pics when you have time.

Took a few pics today but not sure how to post them on this forum. It's a little different from my gun/hunting forums.

First problem I need help with is the throttle is sticking when I try to ease on the gas. It only does this when the car is running, doesn't stick at all when it's off. Any ideas?

Throttle "sticking" only when the engine is running tells me that someone did a "rebuild" if the throttlebody (put bearings in on the shaft for the dreaded loose throttle shaft) and didn't wind the return spring back on it properly OR the throttle shaft is very loose in the bore and the vacuum of the engine running is cocking the throttle blades in their bores.
For the first possibility you'd need to remove the arm from the shaft and get the spring positioned properly.
For the second you'd need a "rebuild" of the throttlebody which involves a bit of machine work to get it apart, opening the shaft bores for the needle bearings to be installed, then a little more drilling and tapping to put it all back together.
I've done a few of the "rebuilds" myself. If you need further advice/info on the process, etc. just PM me.

Congrats, sounds like a sweet ride. use a hosting website like imageshack to host the images. you have to do them one at a time. then when you post a reply, use the image icon and paste the link for the image.

Morley,
The BBK 58mm throttle body was purchased from Summit in Feb. 2006 so nut sure if it has been rebuilt only being one year old. My thought were engine vacuum hold the blades closed. The throttle shaft seems tight to me. I'll check the spring position and go from there.

ZL1,
I've used Photobucket before so I'll give that a try.

Thanks for the help,
Rob

BBK's are known for sticking. If the spring is on wrong, engine vacuum will open the blades.

Since my son and I are no longer looking for a 3rd gen, I'm going to quit using this thread and start a new thread in the "Problem Daignosis" section about the sticking throttle cable.

Thanks for all the help so far!!!!!!

I like all the f-bodies except for the early 2nd gens. I drove my buddy's 79 Z28 with the 350 and it was the shite. Those dual exhaust w/cherrybombs sounded nice. I also like the 77 T/A used in Smokey and the Bandit. I'm hoping to upgrade from my 89 2.8 to my dad's 67 400 in the future.
