Throttle body frustrations!
Throttle body frustrations! I got a Holley 58mm throttle body about a week ago and have had nothing but problems!!! I thought maybe it just threw off the tune a little so I contacted Bryan at pcmforless and he said he does not like that brand cuz the problems hes had with them and I should get a bbk or as&m.
What do you guys think?

let me guess, it sticks open around 2000rpm when you let off the throttle under load...like coming to a red light, etc? It also had all kind of issues with the TPS (which was good). I will be receiving my 3rd Holley 58mm in the mail today, Kyle from Holley assured me it's the NEW design and this particular unit he sent me is 2 weeks old off the assembly line. The other two I had were the older style which had an issue with the throttle body bushings which Kyle @HOlley could explain better than me.
I'd call and talk to him, ship it to him with a list of the problems and an receipt (mine was lost in Hurricane Rita, so they cut me some slack) and they'll either fix it or send you a new design.
All that being said I'm using my buddies 10 yr old BBK58mm, looks ugly as **** IMO but runs better than anything I've used before. Contemplating a new AZM Monoblade but more interested in a 90mm w/SuperVic so undecided.
hope this helps a little.

I got a holley 52 which i posted some stuff on about 2 months ago. I had a problem with the throttle sticking before it hit the stop. This caused me to idle at about 1200-1300 and would make the downshifts rough. I was going to put my stock on again but needed a new gasket. I never ordered the gasket and now about two months later, the idle seems to be okay. Not sure if there was a clearance issue that has worked itself out. But now it idles about 700-800 and has no problems shifting.
I did a little reading before I got the Holley and have heard rumors of the bbk units sticking open at wide open throttle. Search on yahoo or google about it. That eliminated the bbk because something like that would be extremely dangerous. I didn't go with the asm because of the price.
Hope the new tb works well and good luck.

..dude don't believe everything you hear. Not saying modifying certain stock GM parts isn't the best route on some things but for the subject of this post I assure you porting a stock TB doesn't "own" an aftermarket unit. Trending Topics

I guess I should have read up on it a little more before I bought it apparently

Im sure it prolly flows just as well as the aftermarket unit, and you wont have TPS or idling problems.
Now as for the holley's my friends had 2 and both have the same problem. It seems they like to open more than 90* and that will cause a TPS overvolt, and make the car go into limp mode. His solution was he designed a stop from work that will only let it open to the correct angle..

They problem are the blades. They aren't actually circles they are CNCd so the edges actually are flat and triangular. I had the above problems (surprise) and endedup sanding the edges good, so that it's actually round now. I could actually see where it was making contact with the bores... It's a well built piece... but they need to work on thier design.
well I learned something new about stockers being bored to 52mm I guess, that's pretty cool you can do that.
My BRAND NEW HOLLEY 58mm came yesterday, wow what a work of art, sure is purdy, if only it'll work good this time. According to Kyle @Holley it should not give me any more problems.
here is the deal though...think I want to sell it like it is, brand new, in a box, never used...and go to an AZM Mono....hmmm...I'm kicking it around, if I sell it I'll post a link to the FOR SALE section.
