Whistling Throttle Bodies! Does anyone have a solution?

[badstang123]

A while back I installed a Edelbrock Throttle Body, Edelbrock Elbow and a Edelbrock Performer Intake. Since this install I have that annoying whistle on light acceleration. Has anybody come up with a solution to get rid of this. If there is something I can do I would love to know. Otherwise I might block IAC passages, file things down, or do whatever I can until it goes away. Thanks.

If it in the TB and not something else like a Vac leak... than I have heard of numerous people smoothing out the IAC port on the bbk TBs and it was eliminated. I have not tried it yet, I have gotten used to the whistle and really dont notice it. Good luck.

I've heard of two fixes for this:

1. loosen the TPS sensor and slide it one way or the other then retighten (this has been reported as being a temp fix in some cases and permanent in others).

2. pregressively drill the hole in the throttle blade SLIGHTLY larger until whistle goes away

Anytime now, Grady will chime in with his .02.

Maybe look at your stock TB vs. Edelbrock, and see any differences

I had this and drove me NUTS. It was the accufab 80mm, with fox tb set up. I used bolts instead of studs and I guess it didn't seal quite right. When I went to the egr delete it sealed better and no more squeak and no more hesitation.
