Last time I had mine off I was looking at that adjustment. There is a very minor amount of adjustment to not cause the butterflies to feel sticky as they go to far closed and get stuck on the bore. The adjustment may be minor enough to not cause a huge idle increase, that is why I mention it. Just a thought. Also if I remember correct, one of the butterflies closes on an inset plastic part, maybe it swelled up.

Yes, 100% sure it is hanging open, as I said in the first post. I guess it's possible that something else is causing it to idle high as well, but it definitely is sticking open as I have verified several times.

CC, i've got a stock unit that was re-bored to 52mm and upgraded by arizona speed & marine. i purchased it almost new from a forum member 3 years ago as part of a package of other used performance parts he was selling. ended up getting it very cheap. anyway, you might call them and find out of they still perform this service, at least the rebuild part. it will undoubtedly cost less than $350.

just another avenue to ponder. hope this helps.

Dunno, but it might have something to do with why the engine speeds up if you increase the TPS voltage. Wierd, as you do this test with the throttle blades shut the whole time. You'd think if anything it'd just richen it out and make it idle worse or stall.

Back to the top due to Holley being a piece of garbage. Typical problem .... sticking under vacuum, but closes perfectly with engine off. I cleaned the blades, cleaned the return spring. Not too many miles on it.
I had problems with AS&M years ago.
Are there any good brands out there ?

I've been hassling with these TPI throttle bodies for 2 years now and I'm sick and tired of it.
Original TB got sloppy, leaked vacuum at the worn housing. Paid $150 for exchange on a machined with bearings on the shaft. Depending on how I adjusted the shaft end play, it would either hang up at high idle under vacuum, or stick coming off idle. I must have dicked with it and reassembled it 5 times. They are a tedious bitch to reassemble.
Tried a 3rd used throttle body, same crap, idle hangs under high vacuum. Weak springs maybe on this one?
The throttle cable has never been an issue. It only hangs when the car is running, under vacuum, and when it heats up I can watch the throttle stay off the stop by 1/8 inch.
I've f****ng had it with these garbage TBs. I can get a new Delco one for $350, or a new Holley one for $350. I've heard nothing but bad news about the BBKs.
Any suggestions?

Found an old CD with some drag racing with Central Coaster and Shinobi X those were fun days here on the forum, lots has changed since then.
